5 years ago the ratio of Shyam’s age to Ram’s age is 3:2. If Ram’s present age is 25% less than Shyam’s present age. What will be Ram’s age after 10 years?
(A) 20 years
(B) 15 years
(C) 25 years
(D) 20 years
Answer: (C)
Explanation: Say Ram’s present age = R
Shyam’s present age = S
S = R+S/4———————(1)
5 years ago:
(S-5)/(R-5) = 3/2————(2)
from 1 and 2:
(8R/3) -10 = (9R/3) – 15
R =15
After 10 years Ram’s age = 25 years
