Question & Answer GATE 2021

Aptitude Section

Q1.

Solution: Required probability = P(both are even) = P(first is even) * P(second is even) = (3/6)*(3/6) = (1/2)*(1/2)
= 1/4 Answer

Q2.

Solution:

The hatched region is called Secant of a circle. Area of secant = 1/4(Area of circle) – Area of triangle shown
= 1/4 (π r2) – 1/2 (base*height) = 1/4 (π r2) – 1/2 (r*r) = 1/4 (π r2) – 1/2 (r2) = 1/2(π/2 – 1)         [r = 1 given]There are two such Secants, So, area of dotted region surrounded by Secants shown in the question = 2*1/2(π/2 – 1)
= π/2 – 1
Area of square = r*r = 1*1 = 1

Therefore, Required probability = Area surrounded by Secants / Area of square = (π/2 – 1) / 1 = π/2 – 1 Answer
