Question

Product of pragati's age before 2 years and 3 years is 84 then find her present age?

Answer 1

Let present age be x
so ATQ,,,,2 yrs ago= x-2
and 3 yrs hence = x+3
so product =84=(x-2)(x+3

Answer 2

let Pragati's present age be X
2 years ago her age was X - 2
3 years ago her age was X - 3

therefore the product of both of Ages= (X - 2) x (x - 3)

X^2 - 5X + 6 = 84

then find the value of x 3 middle term method

I think this process will help you if so then please mark my answer as brain list
