Question: 3

The sum of A and B's age is 43 years. 11 year hence, A's age will be 7/6 times B's age then. Find B's present age.
  • 22 years
  • 20 years
  • 24 years
  • 19 years

  Show/Hide Explanation 

Correct Answer: D

Let A's age be xx and BB's age be y.
x+y=43x+y=43 -------- (i)
(x+11)=76(y+11)(x+11)=76(y+11)
⇒6x−7y=11⇒6x−7y=11 -------- (ii)
On solving both the equations, we get:
y=19 years
