Question

The sum of the age of a man and his son i8 45.The Product
of their age before 5 years is 124. Find the present age ​

Answer 1

Answer:

9 years

Step-by-step explanation:

Let father's present age be x years.

Son's present age =45−x

Therefore,

⇒(x−5)(40−x)=124

⇒40x−x

2

−200+5x=124

⇒x

2

−45x+324=0

⇒(x−9)(x−36)=0

⇒x=9,36

Clearly x cannot be 9

Therefore,

Father's present age = x=36 years

Son's present age = 45−36=9 years
