Question

A MAN IS 35YEARS OLD AND HIS SON IS 7 YEARS OLD IN HOW MANY YEARS WILL THE SON BE HALF AS OLD AS HIS FATHER

Answer 1

Answer:

Man = x

Son,=y

This is equation 1. x+y=42

equation 2. y=x/2

y=42-x . equation 3

Solving equation 2 and putting value of y.

y=x/2.

42-x=x/2

84-2x=x

84=3x

x=28

Age of father is 28yrs

putting this value in equation 1

28+y=42

y=42-28

• y=14 . This is the answer

Answer 2

Answer:

It will take 7 years for the son to become half of his father's age.

Step-by-step explanation:

Let the number of years be x

35 + x = 14 + 2x

by simplification:

x = 21 years
