[Q] Kamal was 4 times as old as his son 8 years ago. After 8 years, Kamal will be twice as old as his son. Find out the present age of Kamal.
(a) 54
(b) 30
(c) 44
(d) 40

Solution

Answer    (d)
Explanation
----
Let the age of the son before 8 years = x
Then age of Kamal before 8 years ago = 4x

After 8 years, Kamal will be twice as old as his son
=> 4x + 16 = 2(x + 16)
=> x = 8

Present age of Kamal = 4x + 8 = 4×8 + 8 = 40
