Answer 2

Answer:

The present age of Reena is 5 years and present age of Mr. Sunil is 25 years .

Step-by-step explanation:

Reena's age = x

Sunil's age = x^2

After 5 years Reena's age will be x+5

After 5 hears Sunil's age will be x^2+5

We are given that After 5 years Mr. Sunil will be three times as old as Reena.

$x^2+5=3(x+5)$

$x^2+5=3x+15$

$x^2-3x-10=0$

$x^2-5x+2x-10=0$

$x(x-5)+2(x-5)=0$

$(x-5)(x+2)=0$

$x=5,-2$

Since age cannot be negative .

So, age of Reena is 5 years

Age of Mr. Sunil = $x^2 = 5^2 =25 years$

Hence the present age of Reena is 5 years and present age of Mr. Sunil is 25 years .
