Answer 2

Answer:

Step-by-step explanation:

Let Renu mother's age be x

Let Renu's age be y

According to first condition,

x = 4y

According to second condition,

x + 5 = 3(y + 15)

Therefore, x - 3y = 10

Subtracting equation 1 from 2 we get

x - 3y = 10

- (x - 4y) = 0

Therefore, y = 10

Substituting value of Y in equation 1

Therefore , x = 4 × 10

x = 40

Therefore Renu age is 10 years and her mother's age is 40 years
