There were 60 mangosteens altogether in Basket A and Basket B. After I had transferred 4 mangosteens from Basket A to Basket B, the number of mangosteens in Basket A became thrice the number of mangosteens in Basket B. How many mangosteens were there in Basket A at first?
| |
A |
B |
Total |
| Before |
3 u + 4 |
1 u - 4 |
60 |
| Change |
- 4 |
+ 4 |
|
| After |
3 u |
1 u |
60 |
Total number of mangosteens
= 3 u + 1 u
= 4 u
4 u = 60
1 u = 60 ÷ 4 = 15
Number of mangosteens in Basket A in the end
= 3 u
= 3 x 15
= 45
Number of mangosteens in Basket A at first
= 45 + 4
= 49
Answer(s): 49
