There were 51 dragonfruits altogether in Basket A and Basket B. After I had transferred 6 dragonfruits from Basket A to Basket B, the number of dragonfruits in Basket A became twice the number of dragonfruits in Basket B. How many dragonfruits were there in Basket A at first?
| |
A |
B |
Total |
| Before |
2 u + 6 |
1 u - 6 |
51 |
| Change |
- 6 |
+ 6 |
|
| After |
2 u |
1 u |
51 |
Total number of dragonfruits
= 2 u + 1 u
= 3 u
3 u = 51
1 u = 51 ÷ 3 = 17
Number of dragonfruits in Basket A in the end
= 2 u
= 2 x 17
= 34
Number of dragonfruits in Basket A at first
= 34 + 6
= 40
Answer(s): 40
