Prasant says: This time paper was easy but the numericals were difficult. There was no pattern followed for the numericals. Even the obvious topics of numericals were not there.
Raunak says: Question was easy but some numerical were difficult…Overall easy paper..but pattern were not followed…
Rohit says: I Am still confused, half the answers i gave was correct , but after seeing this comments am in a dilemma of even cutt off . I think paper was easy but tricky to make students confuse in the question itself . Half of the students are interested in knowing the answers but i think its more about questions to understand. The whole point is to understand students concerned about the diverse design program in working as well as creative.
Mas says: Who the hell says that paper was easy , it was just like the previous year papers , the only fact is that most of the questions were tempting and made us feel like we know about their answers but reality was somewhat different . A decent paper I must say.
AK says: The paper wasn’t easy by any means. I guess everyone’ been just saying that it was easy. At the max, the cut off may increase by 2-3 marks from the previous year cut off, definitely not more than that.

The Challenge on inclusive growth is accepted.
Corrected answer is (A) or (B) or (C)
Congrats for candidates who challenged the question.
As I expected, No other challenges on answer keys accepted.
How much are you expecting LR?
do iit roorkee (MURP) iit kharagpur (MCP) conduct interview for admission or is it only on gate score? where to find latest information regarding this? the websites dont seem to show anything in particular.
IIT Roorkee conducts interview for M.arch and M.U.R.P both. 30% selection will be based on interview and 70% on the basis of gate score.
what do thy ask in interview …..i took interior in my b.arch…now i want to switch to urban ….is it possible ?
What is the minimum percentage required in B.Arch to get in IITs(IIT Kgp specifically)? Do they consider B.Arch marks at all or admission is just based on your GATE score?
If anyone has challenged the additional built up area question with logic of percentage of A over B = 2.5/10*100 = 25% ??
The Question paper was just as hard as the last one. The only difference is that , they convinced us that the paper was easy by using trick questions.
What will be expected cut off ?
42-45
MJ are you crazy ? For any exam the cutoff moves around 33% – 40% of the highest marks secured.
Use some common sense , the cutoff you are suggesting is nearly 50 %
In 2015 cut off was nearly 43
..so don’t be surprised this time. Nd use ur commonsense as pr paper difficulty nd canditure expected marks..
Paper wasn’t that easy brother I too expect 50+ score, BTW I don’t know whether what you are saying is true or not but still 45 won’ t be the cutoff this year.
2015 qs was conventional type..those who prepared well did good..thats why cut off and highest increased..both in 2016 and 2018 were unconventional pattern, seems easy though after exam..people without preparation did well comparably..and in 2016 gen people got 70+ rank for 50+ marks..in 2017, 45 rank with 58 marks when the paper was tough conventional..no one can actually tell what will happen this time..only hoping for the best.
i think now it all clear..cut off is almost 44…so being a person always try to use ur common sense..
I owe an apology if it hurts . You were right and I feel nothing wrong in admitting it.
Hi Admin, what rank can be expected for 50 mark in general category?
Hi admin, whats the expected rank for score between 47-50.. Can u please give me link to know about last year cutoff of colleges.. TIA
Last year cutoff was 35.2
I am expecting marks around 61. What do you think about the rank?
I am expecting 54 marks, can I expect a rank under 70?
dear admin is 35 marks are safe score for obc category
Any idea regarding the cutoff for general and OBC this year? Is 55 a safe score?
Cut – off for general expecting in the range 34-38 and for OBC 30-35
55 is a good score
This does make me feel hopeful! 🙂 But I’m trying my best to not have high expectations and later deal with disappointment! Let’s hope the qualifying mark is within the expected range! Considering quite a large number of people found the paper easier this year, I’m a bit worried about the cutoff.. Fingers crossed for the results! Good luck everyone!
Hi, for 40 marks.What do you think the rank could be?
Did anyone calculate their score according to the released answer key? How much are you expecting?
65
Anyone planning to challenge that question on inclusive growth?
I think it can be easily challenged as other options are also correct.
Right! And the article is on the official page of UN itself, so the question could be challenged!

Please challenge the question! I think it would work out if a bunch of people challenge it with proper supportive material (like links, pdf etc)

Questions can be challenged from 21st to 23rd.

The question on rainwater collection – 42nd question.
Answer- 14.4 hrs
Its 15, Dont lose your money.
Area = 100 sqm
Rain fall 60mm/hr = .06m/hr
Collection per hour = 6 cum./hr
After 20% loss = 4.8 cum./hr
Time taken to fill the tank completely = 72/4.8 = 15 hrs
Another way to calculate
1 hr – 6 cum. collected – 4.8 cum. stored
10 hr – 60 cum. collected – 48 cum. stored
15 hr – 90 cum. collected – 72 cum. stored
While calculating in your method
you took 1.2×72 = 86.4 cum to be collected
you collected 86.4 cum,
you stored 86.4 x 80/100 = 69.12
In your method you should calculate like below
Total to be collected = y
80% of y stored , y(80/100) = 72
that means ……. 0.8y = 72
y= 72/0.8 = 90cum.
that is 90 cum. has to be collected and we loss 20% of that to collect 72 cum
Time taken to fill the tank completely = 90/6 = 15 hrs
or you should have calculated as 72 x 1/0.8 = 90 cum.
instead of 72 x 1.2
Thank you! I realised the mistake! 🙂
Storage : 1. Act of storing
2. State of being stored
When case 2 is considered by after having read the question 1.e water having been stored in the tank and the loss happening then due to whatever factors(like percolation into the surrounding soil through the walls of the tank or anything else) :
Volume of the tank = 72cum
Loss of 20% = .2*72= 14.4cum
Total volume of storage necessary to fill up the tank in spite of 20% loss = 72+14.4 = 86.4cum
Water collected on the roof /hr = 60mm = .06m
Total volume collected on roof/hr = .06*100 = 6cum
Therefore, necessary time to fill the tank = 86.4/6 = 14.4hrs
The ambiguity in the question lies in the meaning that one attributes to the word “storage”. Is it the ‘process of storing’ or ‘the state of being store’. If you go by the ‘process of storing’ then the answer would be 15. If you go by ‘the state of something being stored’ then the answer would be 14.4.
The above point is valid since they have mentioned about 20% loss during storage (and not during the process of collection) and storage could be thought of as an act of storage or the state of being stored..
LR, is there any question which you think could be challenged?
The question on inclusive growth only. I don’t think any other questions has to be challenged.
This is the only challenge accepted
Can we challenge Q55 of gate paper…the built-up area qestion ..
Site -10 ha
total height -45 m
Option A floor to floor height is 3.6 m
Option B floor to floor height is 4.5m
Therefore
No. Of floor in option A -45/3.6= 12.5
No. Of floor in option B – 45/4.5= 10
So additional built-up achieved by A Shud be 25% not 20%
okay pr , i gave the same answer like you but the way gate guys have solved it is 20 % , coz no. of floors can’t be in decimal , either it can be 12 or 13 and according to the decimal round off rule we have to take 12 (coz its 12.5 , if it was above 12.5 like 12.6 or 12.9 we would have to take 13 as round off digit) so 12-2=2 so the answer is 20% , well i am just telling you the way they have solved you can try your luck . best of luck man …
Thanxx rohit

YES , its Ahemedabad
Yes, Thanks for correction!
53. A building with 100 sqm roof area is connected to a 72 cum rain water collection tank. If the rain fall is 60mm/hr and the loss during water storage 20%, then the time taken to fill the tank completely is __________hrs.
Admin, when calculating the loss of 20%, should it be with respect to the volume of water collected on the roof or the volume of water in the tank? There’s really an ambiguity here.
15 hrs
14.4 hrs if you consider the 20% loss in volume of the storage tank .

Admin, how good is a score of about 55? What would be the approximate gate score for this mark?
A, what can be said is a decent rank & score!
19. According to UN, one of the component for measuring ‘Inclusive growth’ is
A. Economic well-being
B. Physical infrastructure
C. Education
D. Life expectancy
Economic well-being.
Physical infrastructure
https://sustainabledevelopment.un.org/content/documents/739indicators.pdf
page 7?
This question could be challenged! Because economic growth alone isn’t a part of inclusive growth. A number of other factors have been added in the recent times.
And more importantly the article is on the official website of UN itself!
20. Unit of Damp Proof Course (DPC) is
A. kg B. cum C. sqm D. rm
Sqm, but In professional field its rm
Which is correct?
Sqm.. In everyday usage, it is addressed in running meters though it isn’t how DPC is actually calculated.
can we challenge tis qestion …becoz rumning meter is also correct ….?
Ans n soln for qn 60, anyone?
q = (k / s) A dT
= U A dT
for 230 thick wall
q = 2.4 x 50 x 2 = 240 W
for 20 thick concrete block
q = 1.7 x 50 x 2 (Taking temp difference as 2)
= 170 W
change in heat flow is 70W
Admin, for the 56th qn regarding the negative BM, are we supposed to enter the answer as 225 or -225? As it is already mentioned negative in the qn, I’m confused. Are both answers right?
GD, both should be right because it is just a sign convention. Different authors use different sign convention for the same question. Even the official answer of previous year GATE exams could be produced as proof if the examiner doesn’t award marks. (negative sign in the question might have been used as a trap to look like a difficult question to be asked for the first time)
According to my knowledge, there wasn’t any such problem regarding the sign convention fr the past few years. The previous answer keys have solutions ranging from x to y, but not for the sign. Will it be worth challenging the qn in case a problem arises?
14. World Trade Center (WTC) in 2001collapsed due to
A. Wind load failure
B. Foundation failure
C. Thermal performance failure of reinforced steel in RCC
D. Thermal performance failure of structure steel.
answer is D, right?
C , it is mentioned in MIT RESEARCH PAPER
Could you please share the link of the paper? There seems to be different answers (C/D) between different websites.
Kindly give me your email I’d
[email protected]
http://web.mit.edu/civenv/wtc/PDFfiles/Chapter%20VI%20Materials%20&%20Structures.pdf
See page 91
Isn’t the MIT research paper talking about ‘structural steel tubes’ and not reinforced steel in RCC? WTC isn’t a RCC structure.
In case if it was made up of solely the steel tube , you could be right but the core of the structure was made of RCC , READ the whole text carefully.
i also think so
it’s D
It’s not a matter of your thought , it’s the fact that matters
THE COLLAPSE – “As the joists on one or two of the most heavily burned floors gave way and the outer box columns began to bow outward, the floors above them also fell.”
http://www.tms.org/pubs/journals/jom/0112/eagar/eagar-0112.html
As per this journal, I presume the joists refer to structural steel. Please correct me if I’m mistaken.
The question asks about the failure of whole etc and not the outer and inner portion
Absolutely no other report matters before the final report presented by the official body entrusted with the work to examine the failure of WTC. Look into that report!
http://www.tms.org/pubs/journals/jom/0112/eagar/eagar-0112.html
The WTC was primarily a lightweight steel structure;
The major events include the following:
The airplane impact with damage to the columns
The ensuing fire with loss of steel strength and distortion
The collapse, which generally occurred inward without significant tipping
Haven’t you heard of RCC joist !!!!!
Dude, look into the official report. What I have heard or what you have heard doesn’t matter here! Let’s talk sense.
I am not saying you said that , let the answerkeys be issued .

Admin, I’m expecting 50-55 marks, what rank can i expect?
Considering paper was easier than last year I guess around 150-200. Even I am expecting a similar range.
LR, expect better rank. As there are varied range of opinions, it seems difficult to guess.
I am expecting 100 marks , what does it mean , expectation hardly meets reality !!! Please relate your answers with the key IIT-G shall be providing shortly.
I m getting 58 marks …what rank I can expect
Answer for question 50?
Option D is correct.
Link1 for symbol for Emergency Light: http://www.conceptdraw.com/diagram/ceiling-spot-light-symbol
Link2 for symbol for Bio-hazards: https://www.youtube.com/watch?v=MZdnHg3cnYs
https://oae.stanford.edu/resources-faqs/disability-access-symbols
If that is the case what about option 1 , see the link above , it is of Stanford University standards
Anand, in option 1, symbol for Bio-hazards doesn’t match correctly.
I mean it must be Option C
Well the question is ambiguous in itself , an instruction for hearing impaired can be given in a same way as the speech impaired would impart his information.

57. An isolated enclosure shown in the figure has inlet P and outlet Q of 25 sqm each, on the opposite walls. The outdoor wind speed is 5m/sec. If coefficient of effectiveness is 0.6, the rate of natural ventilation in the enclosure due to wind action is __________cum/hr?
Anyone solved?
Wasn’t it inlet and outlet area of 2 sqm each? Anyway, the answer I got was 21600.. Might be incorrect also!
21600..mine too
11. Assuming other variable remaining constant, the “Tropical Summer Index”
A. Increases with increase in air velocity
B. Decrease with increase in WBT (Wet Bulb Temperature)
C. Decrease with increase in global temperature
D. Increase with increase in vapor pressure
Answer D or A
Increases with increase in vapour pressure because rest three possibilities are wrong if you go by the equation for tropical summer index.
A building with 100 sqm roof area is connected to a 72 cum rain water collection tank. If the rain fall is 60mm/hr and the loss during water storage 20%, then the time taken to fill the tank completely is __________hrs.
Is the answer 15 or 14.4?
I think, answer key is released, please now calculate and comment about cutt off . Let’s see if the answers we gave was correct or not , now we can guess for expected cutt off .
Who the hell says that paper was easy , it was just like the previous year papers , the only fact is that most of the questions were tempting and made us feel like we know about their answers but reality was somewhat different .
A decent paper I must say.
The paper wan’t easy by any means. I guess everyone’ been just saying that it was easy. At the max, the cut off may increase by 2-3 marks from the previous year cut off, definitely not more than that..
If anyone has solved, what is be the answer for the 57th question?
Was it 21600? I’m not sure either.. Just a guess!
Yaa 21600
Are you sure??
Admin , what rank can I expect 45-47 , specifically, please according to previous cutt off ??
RR, expected rank could be AIR 250-350. This year cut-off would be higher than the previous year. So, rank@45-47 marks in GATE 2018 would be lower than the previous year.
okay , great , one more thing if i have to use this score for next year then will they consider the rank according to this score ??
RR, GATE score is irrespective of GATE year unless they do not change the formula for calculating GATE score.
I am expecting 47 to 50 with OBC , will I be able to make IIT-kgp
How much is needed for a rank within 100 this year? Is 50+ is a safe score?
Ruma, yep. 50+ is a safe score.
What are my chances of getting IIT-KGP with OBC category and around 40-50 marks.
Anand, mostly it depends on this year cut-off. 40-50 marks range seems not secure. (There is big difference between 40 marks and 50 marks)
What would be my gate score if I have around 44-46 marks
One of the question between 46-49 was
Dead load 18 tonne , live load 12 toner , facto of safety 1.5 and load on column as 10 tonne/ sqm , area of footing in sqm________
Answer : 2 sqm
Isn’t it 4.5 sqm?? 30×1.5=45 and 45/10=4.5 sqm
FOS =
Ultimate Strength / Design Load
yes it is 4.5sq.m
I am expecting around 50 , what rank must I expect in GATE 2018 AR exam.
I’m myself expecting marks around 45-50.
My guess is the rank will be around 300-600.
A decent rank! May be AIR 40 to 100.
Everyone is saying cutoff will be high so I am assuming for 40-100 we’ll be needing 55-60, no?
Let the result come man , if every one is saying so , lets just wait . Is there any one who remember the question no 46-50 ?
What do you expect for OBC category if I am expecting 40-45 marks , will I be able to make IIT-KGP.
it depends upon cut off..if cut off would be similar to last year then ur rank must be around 180-200
I Am still confused, half the answers i gave was correct , but after seeing this comments am in a dilemma of even cutt off . I think paper was easy but tricky to make students confuse in the question itself . Half of the students are interested in knowing the answers but i think its more about questions to understand. The whole point is to understand students concerned about the diverse design program in working as well as creative .
A builder develops 12 hectare site. Developmental cost is 300 million rs per hectare. Assuming the saleable area as 60% calculate the selling price in million per hectare so as to provide the builder a profit of 20%
Ans: 360 ? 600?
At first I thought its 360 but then i read it again and it was 600 . I am still confused!
total developmental cost = 300X12 = 3600 million
profit = 20%
total selling cost = 3600+20%
= 3600+720 = 4320 million
saleable area = 60% of 12 hectare
= .6X12 = 7.2 hectare
selling cost per hectare = 4320/7.2
= 600 million
Is 600 million profit of 20% !!! Think ?
Power supply is 110w. What will be the current if voltage is 330v with power factor 0.8?
Ans: 3.75 a (probably)
P = V I cosφ, cos φ is power factor

29. A 25 storey building has 5 lifts. Resulting waiting time is 35 sec and ‘returning time’ is 175 sec. The no. of lift required for reducing waiting time to 25 sec without increasing lift speed is
7 lifts
We already have 5 lifts, so ans should be 7-5= 2 lifts
What was the question exactly? How many more lifts required or No of lifts required in total?
I guess the question asked total lifts required
More lift required
Ans 2
2
The building already has 5 lifts. So answer is 2 lifts.
Question was The no. of lift required
So the answer is 7
But was confusing, hence probably will give mark for 2 also

2 hectare plot with FAR 2. Ratio of residential to commercial is 3:2 and parking required for residential is 1 ecs per 100sqm, for commercial is 1.25ecs per sqm.
Calculate total ecs
Total buildable area=20000×2=40000Sq.m
Residential area (3/5)x40000=24000sq.m
Commercial=(2/5)x40000=16000Sq.m
No.of ECS for residential =(24000/100)x1=240
No.of Ecs for commercial=(16000/100)x1.25=200
So the total no.of Ecs=440
