Question

Three years back, a father was 24 years older than his son. At present the father is 5 times as old as the son. How old will the son be three years from now?

Answer 1

let father's age is X and son's age is Y
then according to question,
@present
son 's age will be 5 times more than his father's age = 5×Y
hence father's age is 30@present
and son's age is 6 @present

Answer 2

Answer:

According to the statement, 3 years back the father was 24 years older than his son.

Mathematically we can write it like that :

(Y-3)-(X-3) = 24

Now the faher is 5 time older than his son, again we can write it like that :

5x = Y

thats give us a system of linear equation

(Y-3) - ( X - 3) = 24

5X = Y

Where Y is the age of the father and X the age of the son nowadays.

According to this we can easily solve the system by remplacing the Y in the first equation by the 5X in the second equation :

5X -3 - (x - 3) = 24

X= 6

According to X equal 6 we can conclude that X + 3 is the age of the son 3 years from now.
