Q6. A straight line is fit to a data set (ln x, y). This line intercepts the abscissa at ln x = 0.1 and has a slope of −0.02. What is the value of y at x = 5 from the fit?   (2 marks)

 (A) −0.030                  (B) −0.014                   (C) 0.014                     (D) 0.030

Answer: (A)

The equation of a line is

y = mx + c where m is the slope & c is the y-intercept

Now, In this question x is replaced with lnx

So, the equation of line becomes,

y = mlnx + c

or, y = -0.02lnx + c

We have given with abscissa which is essentially x-intercept. So, now we have to find ‘c’ the y-intercept.

for, y=0, lnx = 0.1 (given in the question)

Putting the value,

0 = -0.02×0.1 + c

or, c = 0.002

So, the equation of line becomes,

y = -0.02lnx + 0.002

putting x = 5 (asked in the question)

y = -0.002ln5 + 0.002 = -0.002×1.6 + 0.002 = -0.03

(ln5 = 1.6)

 Q8. Find the area bounded by the lines 3x+2y=14, 2x-3y=5 in the first quadrant.     (2 marks)

(A) 14.95 (B) 15.25 (C) 15.70 (D) 20.35

Answer: (C) 15.25

Q8. lines 3x+2y=14 & 2x-3y=5

Let orange line be, 3x+2y=14

and blue line be, 2x-3y=5

Solving both equation, we get, (x=4 , y=1) the intersection points of the lines.

To get the required area in the first quadrant, we have to deduct the area of the triangle formed by the orange line, blue line & the x-axis from the area bounded by the orange line in the first quadrant.

Area of the triangle = 1/2 x base x height = 1/2 x B x A = 1/2 x 13/6 x 1 = 13/12 ………….(P)

Area bounded by orange line and X & Y axis = (1/2) x (x-intercept) x (y-intercept) = 1/2×14/2×7 = 98/6 …………….(Q)

So, required area = (Q) – (P) = 98/6 – 13/12 = 183/12 = 15.25

 Q1.  The unit of Thermal Conductivity of a material is    (1 mark)
(A) W/(m K) (B) W/(m2 K)
(C) m K/W (D) m2 K/W

Answer: (A ) W/(m K) (Watt per meter per Degree Kelvin)

Possible Intent: The examiner may need to know you the difference between Thermal Conductivity or Thermal Conductance.

k-value – Thermal Conductivity

Thermal conductivity is the time rate of steady state heat flow through a unit area of a homogeneous material induced by a unit temperature gradient in a direction perpendicular to that unit area, W/m⋅K.

k = q(L/T)


L – Thickness of the specimen (m)

T – Temperature (K)
q – Heat flow rate (W/m2)

C-value – Thermal Conductance

Thermal conductance is the time rate of steady state heat flow through a unit area of a material or construction induced by a unit temperature difference between the body surfaces, in W/m2⋅K. C-value, hence, is the reciprocal of the R-value and can be expressed as Equation .

Consequently, the value of the thermal conductance can be calculated by dividing the thermal conductivity with the thickness of the specimen.

Q7.  Low-emissivity coating on a glazing unit     (1 mark)
(A) Increases the SHGC (B) Increases the VLT
(C) Reduces the SHGC (D) Increases the VLT and SHGC

Low emissivity coating on a curtain system leads to:

Answer: (C)

Visible Light Transmission (VLT)

The percentage of visible light that is transmitted through the glazing assembly. This is the essential characteristic for daylighting calculations. A perfectly clear window would have a VLT of 100 percent. Most practical assemblies for architectural use are between 35 and 80 percent.

Solar Heat Gain Coefficient (SHGC)

The percentage of total solar radiant energy that is transmitted through the assembly. This is the essential characteristic for solar gain calculations. For ordinary windows without special coatings, the SHGC and the VLT are the same and sometimes called the shading coefficient (SC). However, with modern coated windows, the SHGC is almost always lower than the VLT. Such window systems are generically referred to as low-emissivity or lowE and are used in most commercial construction.

Q28. In 2001, the population and work force participation rate of a town were 30,000 and 30 percent respectively. The work force participation rate in the year 2011 increased to 34 percent. If the decadal population growth rate was 6 percent, the increase in the number of working people in the town in 2011 was __________  (2 marks)

Answer: 1812

Solution: Working population in 2001 = 9000

In 2011, total population = 30,000 + 6% of 30,000 = 31,800

Now, 34% of 31,800 is the work force = 10812

So, increase in work force = 10812 – 9000 = 1812 Ans.

 Q33.  Find the reverberation time of room 4m x 3m x 3m (LBH) with the help of following data.

  Wall Ceiling Floor
Percentage area 30 70 40 60 100
Absorption coefficient 0.4 0.1 0.6 0.1 0.1


Answer: 0.37 (0.44 to 0.46 answer by official GATE)

Solution: t = 0.16x [(V/A)] = 0.16 [(4x3x3)/15.44] = 0.37 Sec

Calculation of ‘A’

Wall area = perimeter of wall x height = [2(4+3)] x [4] = 56 sqm = P

Ceiling area = 4×3 = 12 sqm = Q

Floor area = 4×3 = 12 sqm R

So, A = P[(0.4 x 30%) + (0.1 x 70%)] + Q[(0.6 x 40%) + (0.1 x 60%)] + R (0.1 x 100%)

= P[(0.4 x 0.3) + (0.1 x 0.7)] + Q[(0.6 x 0.4) + (0.1 x 0.6)] + R (0.1 x 1)

= 56[(0.4 x 0.3) + (0.1 x 0.7)] + 12[(0.6 x 0.4) + (0.1 x 0.6)] + 12 (0.1 x 1)

= 56(0.12 + 0.07) + 12(0.24 + 0.06) + 12 x 0.1

= 56 x 0.19  + 12 x 0.3 + 1.2

=  10.64 + 3.6 + 1.2

= 15.44

Q35. A four-storey building with equal areas in each floor is required to be designed on a plot with FAR of 2.0. If the FAR is increased to 2.2, the percentage increase in ground coverage utilizing full FAR in both cases will be ___________  (2 marks)

Answer: 10

Solution: Let site area be 100 unit. FAR = 2 means built up area = 2×100 = 200 unit. As each floor has equal area, so each floor area = 200/4 = 50 unit. So ground coverage = 50 sqm.

In the second case, site area = 100 unit. Built up area = 220 as FAR=2.2

Ground coverage = 220/4 = 55

So ground coverage is increased from 50 to 55. Therefore, change in % = 10%

Q43. A solar photo-voltaic system is proposed to be installed at the roof top of a hostel. The cost of installation and the annual maintenance are INR 2,40,000 and INR 6000 respectively. It is expected to generate 600 kWh of electricity per month. Assume unit price of electricity as INR 5. Ignoring the discount rate, the payback period of the investment in years is____________   (2 marks)

Answer: 8

Solution: Let the payback time be ‘P’ year.

So, 240000 + 6000P = 600x5x12xP

⇒  240000 +6000P = 36000P

⇒  240000 = 30000P

⇒  P = 8 Years

Q44. In a housing project, the number of LIG, MIG and HIG units are in the ratio of 1:1:2. The ratio of areas of the units is 3:5:8. Assume unit cost of construction is same for all the three types. For a no profit no loss situation, if 10% discount is offered to LIG and MIG units on sale price, extra charge in percentage payable per HIG unit will be ____________  (2 marks)

Answer: 5

Solution: Let,

No. of LIG = 1

No. of MIG = 1

No. of HIG = 2


Total area of LIG = 1×3 = 3 unit

Total area of MIG = 1×5 = 5 unit

Total area of HIG = 2×8 = 16 unit


Also assume,

Cost of construction for all LIG = 3unit

Cost of construction for all MIG = 5unit

Cost of construction for all HIG = 16 unit


As 10% is on LIG, so 10% 3 unit = 0.3 would be burden on HIG

As 10% is on MIG, so 10% 5 unit = 0.5 would be burden on HIG


Total 0.3 + 0.5 = 0.8 would be burden on HIG cost which totals 16 unit

So, % change in cost = (0.8/16)x100% = 5%

Q46. A pump is installed in an apartment building to lift water from ground level to the roof top water tank with the capacity of 10,000 litres. Total head of lift is 18 m and pumping time is 30 minutes to fill the tank completely. Assuming acceleration due to gravity (g) as 10 m/sec2 and efficiency of the pump as 80 percent, the power requirement of the pump in kW will be __________     (2 marks)

Answer: 1.25

Solution: Power = Energy/ Time = Work Done/ Time = Mgh/30min = 10000x10x18/1800 sec = 1000

As the pump is woking at 80% efficiency, power = 10/8 (1000) =1250 Watt =1.25 Watt

Basics of illumination

angle of incidence of 60o with the center of the work plane. The illumination at the centre of the work plane in Lux is __________  (2 marks)

Answer: 100 (by GATE official)

Solution: E(lux)= [ candela /distance square ]* Cosθ = [3200/4]*Cos60 = [800]*0.5 = 400

Basics: The “brightness” of light can mean different things: for example, the amount of light coming from a light source is luminous flux (lumens), the amount of light falling on a surface is illuminance (lux), and the amount of light reflected off a surface is luminance (cd/m2).

Q52. A steel I-beam section is subjected to a bending moment of 96 kN-m. The moment of inertia of the beam section is 24,000 cm4. The bending stress at 100 mm above the neutral axis of the beam in MPa will be ____________   (2 marks)

Answer: 40

Solution: Bending stress = 96x1000x0.1/24000×10^-8 = 40 x 10^6 Pa = 40MPa

Bending stress = (My)/I
M = the internal bending moment about the section‘s neutral axis
y = the perpendicular distance from the neutral axis to a point on the section
I = the moment of inertia of the section area about the neutral axis

 Q55. A 250 mm × 250 mm RCC column is reinforced with one percent steel. The permissible compressive stress of concrete and steel are 8 N/mm2 and 150 N/mm2 respectively. The axial load carrying capacity of the column in kN is _____________     (2 marks)

Answer: 261 (585 – 595 by GATE official)


Pu =0.4 fck Ac + 0.67 fy Asc

Pu = 0.4 x8 x 0.0625(1-1/100) + 0.67 x 150 x 0.0625×1/100 = 0.198+ 0.063 = 0.261 = 261kN


Pu= factored axial load on the member,

fck= characteristic compressive strength of the concrete,

Ac= area of concrete,

fy= characteristic strength of the compression reinforcement, and

Asc= area of longitudinal reinforcement for columns.

  2. in Q.33 calculation of reverberation time problem, total Area of wall is given as Perimeter X Height where height from the given question is 3m. But the solution uses 4m as height.
    Please clarify.

      1. Thank you admin. thereforethe solution changes,
        t= 0.16 x [(V/A)] = 0.16x[(4x3x3x)/12.78] = 0.45 Sec
        Calculation of ‘A’
        Wall area (P) = Perimeter of wall x Height
        = [2(4+3)]x3 = 14×3 = 42 Sqm
        Ceiling (Q) = 4×3 = 12 Sqm
        Floor Area (R) = 4×3 = 12 Sqm

        A = P [(0.4×30%) + (0.1 x 70%)] +
        Q [(0.6 x 40%) + (0.1 x 60%)] +
        R [0.1x 100%]
        A = (42x 0.19) + ( 12x 0.3) + 1.2
        = 7.98 + 3.6 + 1.2

        A = 12.78
        So the answer would be 0.45 Sec
