(A) 32.5 years
(B) 24.9 years
(C) 27.5 years
(D) 29.6 years
Correct Option is: D
Let age of John be y
Smith is 18 years elder than John = (y + 18).
So Smith age 8 years ago = (y + 18 – 8)
John age before 8 years = (y – 8)
8 years ago, Smith is 6 times as old as John
(y + 18 – 8) = 6 (y – 8)
(y + 10) = (6y – 48)
5y = 58
y = 11.6
John age = 11.6years
Smith age = (y + 18) = (11.6 + 18) = 29.6years
