Answer 2

Answer:

The present age of Ramu is 6 years

Step-by-step explanation:

Let the present age of Ramu be x

Ramu's age 5 years ago = x-5

Ramu's age 9 years later  = x+9

We are given that The product of Ramu's age 5 years ago and his age 9 years later is 15.

So, $(x-5)(x+9)=15$

$x^2+9x-5x-45=15$

$x^2+4x-60=0$

$(x-6)(x+10)=0$

$x=6,-10$

Since age cannot be negative .

So, The present age of Ramu is 6 years
