Question

Sue is two years older then Lily who is twice as old as Heather. if the total ages of all the girls is 27, how old is each girl?

Answer 1

sue = 12

lily = 10

heather = 5

Explanation:

'l' = lily's age

'h' = heather's age

sue = 'l + 2' but, since 'l' is 2h we can say sue's age is '2h+2'

l = 2h

2h+2 + 2h + h = 27

5h = 25

h = 5

l = 2(5) = 10

sue is 10+ 2, or 12
