Question

Mr burns is three times as old as smithers. Nine years ago the sum of their ages was 114. How old are they now

Answer 1

Step-by-step explanation:

Let the age of smither be x and burns be y.

x=3y----(1)

(x-9)+(y-9)=114

x+y=114-18=96.-----(2)

(2) in (2):

3y+y=96

4y=96

y=96/4=24.----(3)

(3) in (1):

x=24(3)=72.

Age of smither is 72 years and age of Burn is 24 years.
