Answer»

Let M be the MOTHER’s present AGE and D be the daughter’s present age.

A mother is FIVE times older than her daughter.

M = 5D

After 5 years, she would be three times older than her daughter

M + 5 = 3D + 15

Solving the two equation,

5D + 5 = 3D + 15

2D = 10

Therefore, D = 5

Hence, M = 5D = 25

Thus mother’s present age is 25YRS.
