The ratio of pomegranates to pears is 3 : 4. If 18 pears are added, the ratio of pomegranates to pears will be 3 : 7. How many less pomegranates than pears are there in the end?
| |
Pomegranates |
Pears |
| Before |
3 u |
4 u |
| Change |
|
+ 18 |
| After |
3 u |
7 u |
The number of pomegranates at first and in the end remains unchanged.
Number of pears added
= 7 u - 4 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Number of less pomegranates than pears in the end
= 7 u - 3 u
= 4 u
= 4 x 6
= 24
Answer(s): 24
