Answer 1

Answer:

5 years old

Step-by-step explanation:

Let Raja be x years old now.

Raja will be 4 times his present age.

x + 15 = 4x

3x = 15

x = 5

Answer: He is 5 years old

Answer 2

Let Raja's present age be x years.

By condition,

x + 15 = 4x

4x - x = 15

3x = 15

Hence, x=5

Therefore, his present age is 5years.
