Answer 1

Step-by-step explanation:

First case,

Let Rakhi's age, be = m

Rakhi's mother's age will be = 4m

After five years

Rakhi's age = m+5

Rakhi's mother's age = 4m+5

According to the question,

4m+5 = 3(m+5)

4m+5 = 3m+15

4m-3m = 15-5

m = 10

Thus, Rakhi's age, = 10

mother's age = 4 x 10 = 40

After 5 years,

Rakhi = 15 years old

Mother = 40 + 5 = 45 years old
