Age Problem
Father is aged three times more than his son Sunil. After 8 years, he would be two and a half times of Sunil age. After further 8 years, how many times would he be of Sunil age?
A. 4 times
B. 4 times
C. 2 times
D. 3 times
Read Solution (Total 7)
-
- Assume that Sunil's present age = x.
Then father's present age = 3x + x = 4x
After 8 years, fathers age = 2 ½ times of Sunils' age
=> (4x+8) = 2 ½ × (x+8)
=> 4x + 8 = (5/2) ×(x + 8)
=> 8x + 16 = 5x+ 40
=> 3x = 40-16 = 24
=> x = 24/3 = 8
After further 8 years,
Sunil's age = x + 8+ 8 = 8+8+8 = 24
Father's age = 4x + 8 + 8 = 4 × 8 + 8 + 8 = 48
Father's age/Sunil's age = 48/24 = 2

- let sunils s present age be x years. Then, father's present age =(x + 3x) years = 4x years.
(4x + 8) = 5/2 (x + 8)
8x + 16 = 5x + 40
3x = 24
x = 8.
Hence, required ratio =(4x+16/x+16)=48/24
ans=2 times

- none of these.
ans is : 11/5 times.

- father`s present age = x(let) and sunil`s present age = y
ATQ, x = 3y + y
after 8 yrs, x +8 = 5/ 2 (y+8)
calculating , y = 8 and x = 32 which are present age of sunil and his father
after further 8 years, sunil = 8 +8+ 8 = 24
father = 322 +8 +8 = 48
thus father will 2 times of sunil`s age
