Answer 1

Step-by-step explanation:

Let kruti's present age= x

Kruti's mother present age= 4x

Kruti's age after 5 years= x+5

Kruti mother age after 5 years = 4x+5

4x+5=3(x+5)

4x+5= 3x+15

4x-3x=15-5

X=10

Therefore Kruti age is 10 years.

Answer 2

Answer:

The present age of Kruthi  is 10 years

Step-by-step explanation:

Given,

The present age of Kruti's mother is four times Kruti's age.

After 5 years, the age of her mother is three times her age.

To find,

The present age of Kruthi

Solution:

Let 'x' be the present age of Kruthi

Since The present age of Kruti's mother is four times her age,

the present age of Kruthi's mother is 4x

After 5 years,

Kruthi's age = x+5

Kruthi's mother's age = 4x+5

Since after 5 years the age of her mother is three times her age, we have

4x+5 = 3(x+5)

4x +5 = 3x +15

4x - 3x = 15 -5

x = 10

The present age of Kruthi  is 10 years
