There were 54 pears altogether in Basket A and Basket B. After I had transferred 9 pears from Basket A to Basket B, the number of pears in Basket A became twice the number of pears in Basket B. How many pears were there in Basket A at first?
| |
A |
B |
Total |
| Before |
2 u + 9 |
1 u - 9 |
54 |
| Change |
- 9 |
+ 9 |
|
| After |
2 u |
1 u |
54 |
Total number of pears
= 2 u + 1 u
= 3 u
3 u = 54
1 u = 54 ÷ 3 = 18
Number of pears in Basket A in the end
= 2 u
= 2 x 18
= 36
Number of pears in Basket A at first
= 36 + 9
= 45
Answer(s): 45
