Answer 2

$\huge\bold\colorbox{blue}{卂几丂山乇尺:}$

❥︎ Let Vinu's age be x years & so, Anu's age will be (x + 4) years. [Because Anu's age is 4 years more than vinu's age.]

❥︎ When 4 is added to their product, we get 169.

➪ (x)(x + 4) + 4 = 169

➪ x² + 4x + 4 = 169

➪ x² + 4x + 4 - 169 = 0

➪ x² + 4x - 165 = 0

➪ x² + 15x - 11x - 165 = 0

➪ x(x + 15) - 11(x - 15) = 0

➪ (x+15) (x-11) = 0

➪ x= (-15) or x = 11

The age can't be negative.

➪ x = 11 years

Hence, the age of Vinu is 11 years.

Anu's age is (x+4) years.

➪ 11 + 4 = 15 years

Hence, the age of Anu is 15 years.
