age What is Ravi's present age​

Answer 1

Answer:

Solution:

Let Ravi’s present age be x years.

After fifteen years, Ravi’s age = 4x years.

Fifteen years from now, Ravi’s age = (x+15) years.

According to question, 4x = x + 15

\Rightarrow\ 4x-x=15⇒ 4x−x=15

[Transposing x to L.H.S]

3x = 15

\Rightarrow\ \frac{3x}{3}=\frac{15}{3}⇒  

3

3x

​  

=  

3

15

​  

 

[Dividing both sides by 3]

x = 5 years.

Hence, Ravi’s present age be 5 years.
