Answer 2

Answer:

Ravi’s present age will be 5.

Solution:

From the given, Let Ravi’s present age is taken as "a" years.

After 15 years, his age = (a+15) years.

By the given, it is identified that the age of Ravi after 15 years is equal to the 4 times of his present age.

Given,

\begin{lgathered}\begin{array} { c } { a + 15 = 4 a } \\\\ { 4 a - a = 15 } \\\\ { 3 a = 15 } \\\\ { a = \frac { 15 } { 3 } } \\\\ { a = 5 } \end{array}\end{lgathered}

a+15=4a

4a−a=15

3a=15

a=

3

15

a=5

Then, it has been found that the present age of Ravi is 5 when his age after 15 years will be 4 times of his present age
