Question

Product of pragati's age 2 years ago and 3 years hence is 84 find her present age.
​

Answer 1

The present age of Pragati will be 9 years.

Solution:

Given,  

84 will be the product of her age before 2 years and after 3 years of her present age.

Let x be her present age,

Her age, two years ago will be (x-2)

Her age, three years hence will be (x+3)

According to the question,

Hence, we cannot represent age as a negative value. The value of x will be 9 only.

Therefore, the present age of Pragati will be 9 years.
