There were 48 guavas altogether in Basket A and Basket B. After I had transferred 9 guavas from Basket A to Basket B, the number of guavas in Basket A became thrice the number of guavas in Basket B. How many guavas were there in Basket A at first?
|
A |
B |
Total |
Before |
3 u + 9 |
1 u - 9 |
48 |
Change |
- 9 |
+ 9 |
|
After |
3 u |
1 u |
48 |
Total number of guavas
= 3 u + 1 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Number of guavas in Basket A in the end
= 3 u
= 3 x 12
= 36
Number of guavas in Basket A at first
= 36 + 9
= 45
Answer(s): 45
