George is 8 years more than christopher and ford is 2 years younger than christopher. the sum of their ages is 60. find the ages of george, christopher and ford.

Let us consider that Christopher is 'x' years old

Age of Christopher =  x

George is 8 years more than Christopher

Age of George = (x + 8)

Ford is 2 years younger than Christopher

Age of Ford = (x - 2)

Now the sum of their ages is 60

∴ x + (x + 8) + (x - 2) = 60
3x + 6 = 60
3x = 60 - 6
3x  = 54
x = 54 ÷ 3
x = 18

Age of Christopher = x = 18 years
Age of George = (x + 8) = 18 + 8 = 26 years
Age of Ford = (x - 2) = 18 - 2 = 16 years

The sum of all their ages = 18 + 26 + 16 = 60 years

The amount used= 13.04- 1.9 = 11.14
