Answer 2

Answer:

If 3/7 of the age of Ravi is added with 1.5 years, then the result is half of Ravi's present age. Then his present age is 21 years

Step-by-step explanation:

Let us take Ravi's present age as x

Then, 3/7 of Ravi's age is 3x/7

Given that, when 1.5 years is added to it, it will be half of his age

Let us take 1.5 = 3/2

So,

$\frac{3x}{7} +\frac{3}{2}=\frac{x}{2} \\\\\frac{3x}{7} = \frac{x}{2} -\frac{3}{2} \\\\\frac{3x}{7}=\frac{x-3}{2} \\\\2*3x = 7(x-3)\\\\6x = 7x-21\\\\7x -6x = 21\\\\x = 21$

So, the present age of Ravi is 21 years
