Question

The product of Aromals age before 5 years and his age after 9 years is 15.Find his present age​

Answer 1

Answer:

present age - 6 yrs

Step-by-step explanation:

let his present age be x

as per given condition,

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

X^2-(5)X+(9)X-60=0

X^2+(4)x-60=0

x^2+(10)x-(6)x-60=0

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

(x+10)=0  OR  (x-6)=0

hence, x=/= -10

so,x=6
