IBPS RRB Office Assistant 13 Nov 2016 Paper

(1) 6 years ago,
Kunal’s age = 6x years
Sagar’s age = 5x years
According to the question,
After 4 years from today,

6x+10

5x+10

=

11

10

⇒ 60x + 100 = 55x + 110
⇒ 60x – 55x = 110 – 100
⇒ 5x = 10 ⇒ x =

10

5

= 2
∴ Sagar’s present age
= (5x + 6) years
= (5 × 2 + 6) years
= 16 years
