RRB Group-D Model Paper 13 with answers for online practice

Given:
3 years ago, ratio of Maya’s and Shika’s age was = 5 : 9
Calculation:
3 years ago, ratio of Maya’s and Shika’s age was = 5x : 9x
According to the question
(5x + 8) / (9x + 8) = 3/5
⇒ 5 × (5x + 8) = 3 × (9x + 8)
⇒ 25x +40 = 27x + 24
⇒ 27x – 25x = 40 – 24
⇒ 2x = 16
⇒ x = 16/2
⇒ x = 8
3 years ago age of Maya = 5 × 8 = 40
∴ Present age of Maya = 40 + 3 = 43 years
