There were 57 kiwis altogether in Basket A and Basket B. After I had transferred 4 kiwis from Basket A to Basket B, the number of kiwis in Basket A became twice the number of kiwis in Basket B. How many kiwis were there in Basket A at first?
|
A |
B |
Total |
Before |
2 u + 4 |
1 u - 4 |
57 |
Change |
- 4 |
+ 4 |
|
After |
2 u |
1 u |
57 |
Total number of kiwis
= 2 u + 1 u
= 3 u
3 u = 57
1 u = 57 ÷ 3 = 19
Number of kiwis in Basket A in the end
= 2 u
= 2 x 19
= 38
Number of kiwis in Basket A at first
= 38 + 4
= 42
Answer(s): 42
