Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

Step-by-step explanation:

so let the present age of sunita be x years

so according to the given condition

(x-2)(x+4)=2x+1

ie x.square+4x-2x-8=2x+1

ie x.square+2=2x+1+8

ie x.square=9

taking square roots on both sides

we get

x=3 or x=-3

but as age is never negative x=-3 is absurd

hence x=3

thus present age of sunita is 3 years
