Question

Fiona is 7 years older than Gavin. Alex is 12 years younger than Gavin. If the total of their ages is 73, how old is the youngest of them?

Answer 1

Answer:

let age of Gavin is x

Fiona's age x+7

Alex's age x-12

sum of their age 73 years

so ,

x + x + 7 + x - 12 = 73

3x = 73 -5

3x = 68

x = 68/3

x = 22.66 years

age of Gavin 22.66years

age of Fiona 22.66 +7=29.66 years

age of Alex 22.66-12=10.66years
