There were 51 pears altogether in Basket A and Basket B. After I had transferred 11 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 + 11 |
1 u - 11 |
51 |
Change |
- 11 |
+ 11 |
|
After |
2 u |
1 u |
51 |
Total number of pears
= 2 u + 1 u
= 3 u
3 u = 51
1 u = 51 ÷ 3 = 17
Number of pears in Basket A in the end
= 2 u
= 2 x 17
= 34
Number of pears in Basket A at first
= 34 + 11
= 45
Answer(s): 45
