The ages of Khushi and Jagriti are in the ratio of 5 : 8 respectively. After 8 years the ratio of their ages will be 3 : 4. What is the difference in their ages?
A) 16 years
B) 8 years
C) 10 years
D) 12 years
E) None of these

Read Solution (Total 3)

E) None of these

If present age of Khushi= K and Jagriti=J, then
K/J=5/8 or 8K- 5J=0 ---(i) and
(K+8)/( J+8)= 3/4 or 4K -3J= -8 ---(ii)
On solving (i) & (ii), J=16, K=10
So difference of their ages=16 -10= 6 years
