Answer 1

Answer:

Step-by-step explanation:

Let pragati's age be x years

now, two years ago pragati's age was (x-2) years

        three  years hence(after) her age becomes (x+3 years

product of  her age 2 years ago and 3 years hence = 84

(x-2)*(x+3) = 84

$x^{2}$+3x-2x-6 = 84

$x^{2}$+x-6 = 84

$x^{2}$+x = 78

x = 78 - $x^{2}$
