Answer 2

Step-by-step explanation :

Let, Devi’s present age be x years.

Then, Devi’s mother present age be 3x years .

$\:$

Five years ago Devi’s age = x - 5 years

Five years ago Devi’s mother age = 3x - 5 years

$\:$

According to the question :

⇉ 4 ( x - 5) = 3x - 5

⇉ 4x - 20 = 3x - 5

⇉ 4x - 3x = 20 - 5

⇉ x = 15

$\:$

∴We get the value of x = 15 years.

$\:$

Devi’s present age, x = 15 years

Devi’s mother present age, 3x

= 3 × 15 = 45 year's
