Asked by Edward

Ama is four times as old as Akua. In ten years time Ama will be twice as old as Akua. Find the age of Akua.
Answered by Edward
2 and 20
Answered by oobleck
20 is not 4 times 2.
If Akua's age is x, then
4x+10 = 2(x+10)
x = 5
check:
So they are now 5 and 20
In 10 years, they will be 15 and 30
