Q:
A) 8, 72 yrs | B) 16, 65 yrs |
C) 12, 84 yrs | D) 10, 60 yrs |
Answer: A) 8, 72 yrs
Explanation:
Explanation:
Let the present ages be K,M
Given K/M = 4/5
5K - 4M = 0 ......(1)
Also given that,
M - (K + 5) = 3
M - K = 8 .........(2)
Then, by solving (1) & (2)
M = 40 yrs and K = 32 yrs
Hence, Total of ages = 40 + 32 = 72 yrs
Difference of ages = 40 - 32 = 8 yrs.
