There were 48 lemons altogether in Basket A and Basket B. After I had transferred 7 lemons from Basket A to Basket B, the number of lemons in Basket A became thrice the number of lemons in Basket B. How many lemons were there in Basket A at first?
| |
A |
B |
Total |
| Before |
3 u + 7 |
1 u - 7 |
48 |
| Change |
- 7 |
+ 7 |
|
| After |
3 u |
1 u |
48 |
Total number of lemons
= 3 u + 1 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Number of lemons in Basket A in the end
= 3 u
= 3 x 12
= 36
Number of lemons in Basket A at first
= 36 + 7
= 43
Answer(s): 43
