Answer 2

Given :

• Fathers present age is 4 times Suman’s age.
• After 5 years Father’s present age will be 3 times Suman’s age.

To find :

• Their present ages =?

Step-by-step explanation :

Let, the present age of Suman’s be, x.

Then, the present age of her father's be, 4x.

After 5 years Suman’s age = x + 5.

After 5 years her father's age = 4x + 5.

According to the question :

4x + 5 = 3(x + 5)

4x + 5 = 3x + 15

4x - 3x = 15 - 5

x = 10.

Therefore, We got the value of, x = 10.

Hence,

The present age of Suman’s, x = 10 years

Then, the present age of her father's, 4x = 4 × 10 = 40 years
