Question

Product of ramu's age 5 years ago with his age 9 years later is 15 find dramas age

Answer 1

Step-by-step explanation:

let present age of Ramu be x

age of Ramu 5 years ago=x-5

age of Ramu 9 years later=x+9

ATQ,

(x-5)(x+9)=15

x²+9x-5x-45=15

x²+4x-45-15=0

x²+4x-60=0

x²+10x-6x-60=0

x(x+10)-6(x+10)=0

(x-6)(x+10)=0

x=6

x=-10, rejected as x is age and age cannot be negative

therefore

present age of Ramu=6 years
