SSC GD 2023 PYQ — Question 47

The correct answer is option 3 i.e. $41 {{2} \over 3}$%.

Calculations:

If 85% of (x - y) = 35% of (x + y)

⇒ 85 × (x - y) = 35 × (x + y)

⇒ 17 × (x - y) = 7 × (x + y)

⇒ 10x = 24y

⇒ x/y = 12/5

Let the value of x and y be 12z and 5z.

Required percentage = (5z/12z) × 100 =  $41 {{2} \over 3}$%
