Question

The product of Sunita’s age (in years) two years ago and her age four years from now is one more than twice her present age. What is her present age?

Answer 1

let Sunita's present age be x years
her age before 2 years = x - 2 years
her age after 4 years = x + 4 years
Acc to question
(x-2)(x+4) = 2x + 1
x² + 4x - 2x - 8 = 2x + 1
x² + 2x - 2x - 8 - 1 = 0
x² - 9 = 0
x² = 9
x = √9
x = 3
Sunita's present age = 3 years
