Question

The ratio of meera's age to rina's is 3:8. the difference of their ages is 35 years. the ratio of their ages after 4 years will be:

Answer 1

M : R = 3: 8
let meera's age = 3a
then rina's age = 8a
difference = 5a = 35
a = 7
M = 21 , R = 56
after 4 years their ages = 25, 60
ratio = 25:60 = 5:12

Answer 2

The ratio is 3:8
Let the common multiple be x.
Then, Meera's age=3x; Rina's age=8x

As per given condition,
8x-3x = 35
5x = 35
x = 7

So, Meera's age is 21; Rina's age is 56.

After 4 years their ages will be 25&60.

So, the ratio will be;
25/60 = 5/12
