SSC CGL 2024 PYQ — Question 61

The correct answer is Option 4 i.e. 1.

Put π = 180°

In Option 1 

$\frac{\pi}{6},\frac{\pi}{3}\frac{\pi}{2}$

⇒ 180/6, 180/3, 180/2

⇒ 30, 60, 90

Sum of the angles = 30 + 60 + 90 = 180

In Option 2 

$\frac{\pi}{3},\frac{\pi}{3}\frac{\pi}{2}$

⇒ 180/3, 180/3, 180/2

⇒ 60, 60, 90

Sum of the angles = 60 + 60 + 90 = 210 (Can't possible)

In Option 3 

$\frac{\pi}{6},\frac{\pi}{3}\frac{\pi}{4}$

⇒ 180/6, 180/3, 180/4

⇒ 30, 60, 45

Sum of the angles = 30 + 60 + 45 = 135 (Can't possible)

In Option 4 

$\frac{\pi}{2},\frac{\pi}{2}\frac{\pi}{3}$

⇒ 180/2, 180/2, 180/3

⇒ 90, 90, 60

Sum of the angles = 90 + 90 + 60 = 240 (Can't possible)
