There were 45 guavas altogether in Basket A and Basket B. After I had transferred 4 guavas from Basket A to Basket B, the number of guavas in Basket A became four times the number of guavas in Basket B. How many guavas were there in Basket A at first?
|
A |
B |
Total |
Before |
4 u + 4 |
1 u - 4 |
45 |
Change |
- 4 |
+ 4 |
|
After |
4 u |
1 u |
45 |
Total number of guavas
= 4 u + 1 u
= 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Number of guavas in Basket A in the end
= 4 u
= 4 x 9
= 36
Number of guavas in Basket A at first
= 36 + 4
= 40
Answer(s): 40
