The ratio of grapefruits to persimmons is 3 : 4. If 32 persimmons are added, the ratio of grapefruits to persimmons will be 3 : 8. How many more persimmons than grapefruits are there in the end?
| |
Grapefruits |
Persimmons |
| Before |
3 u |
4 u |
| Change |
|
+ 32 |
| After |
3 u |
8 u |
The number of grapefruits at first and in the end remains unchanged.
Number of persimmons added
= 8 u - 4 u
= 4 u
4 u = 32
1 u = 32 ÷ 4 = 8
Number of more persimmons than grapefruits in the end
= 8 u - 3 u
= 5 u
= 5 x 8
= 40
Answer(s): 40
