Answer 1

Answer:

Let the present age of Ravi = m year

Age of Ravi after 15 years = m + 15 year

According to question, age of Ravi will be four times of his present age.

i.e. Age of Ravi after 15 year = 4 x present age of Ravi

⇒

m

+

15

=

4

×

m

⇒

m

+

15

=

4

m

After transposing m to RHS, we get

15

=

4

m

–

3

⇒

15

=

3

m

After dividing both sides by 3, we get

15

3

=

3

m

Or,

m

=

5

Thus, Ravi’s present age = 5 year Answer
