The sum of present age of P and Q is 48 years. Today Q is 4 years older than R . The respective ratio of present age of P and R is 4 : 7. What is Q's age two year hence ( in years ) ?
Answer & explanation
Correct answer: option 3
It is given that -
P + Q= 48
Q = R + 4
Then,
P +R = 44
ratio of → P : R
4 : 7
Let age of P = 4x
age of R = 7x
As, 11x = 44
1x = 4
age of R = 7x
= 7 × 4 = 28
Q = 28 + 4 = 32
Q age two year hence = 32 + 2 = 34 years
