Step-by-step explanation:

Let present age of Rakhi = x years

Present age of Mother = 4x

5 years later

Age of Rakhi = x + 5

Ag of Mother =4x + 5

Given 4x+5=3(x + 5)

4x−3x=15−5

=> x=10

Mother's age = 4x= 40 years

∴ 40 years is the answer

Answer:

Let rakhi's age be x

let her mothers age be 4x

After 5 years :-

4x +5 = 3( x+5)

= 4x + 5 = 3x + 15

4x - 3x = 15 - 5

x = 10.

4x = 4 × 10 = 40.

Hence rakhi's age = 10 years.

Her mother's age = 40 years .
