There were 60 grapefruits altogether in Basket A and Basket B. After I had transferred 5 grapefruits from Basket A to Basket B, the number of grapefruits in Basket A became five times the number of grapefruits in Basket B. How many grapefruits were there in Basket A at first?
|
A |
B |
Total |
Before |
5 u + 5 |
1 u - 5 |
60 |
Change |
- 5 |
+ 5 |
|
After |
5 u |
1 u |
60 |
Total number of grapefruits
= 5 u + 1 u
= 6 u
6 u = 60
1 u = 60 ÷ 6 = 10
Number of grapefruits in Basket A in the end
= 5 u
= 5 x 10
= 50
Number of grapefruits in Basket A at first
= 50 + 5
= 55
Answer(s): 55
