The ratio of mangoes to pomegranates is 3 : 7. If 12 pomegranates are added, the ratio of mangoes to pomegranates will be 3 : 11. How many more pomegranates than mangoes are there in the end?
| |
Mangoes |
Pomegranates |
| Before |
3 u |
7 u |
| Change |
|
+ 12 |
| After |
3 u |
11 u |
The number of mangoes at first and in the end remains unchanged.
Number of pomegranates added
= 11 u - 7 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of more pomegranates than mangoes in the end
= 11 u - 3 u
= 8 u
= 8 x 3
= 24
Answer(s): 24
