The ratio of pears to pomegranates is 3 : 7. If 16 pomegranates are added, the ratio of pears to pomegranates will be 3 : 11. How many less pears than pomegranates are there in the end?
| |
Pears |
Pomegranates |
| Before |
3 u |
7 u |
| Change |
|
+ 16 |
| After |
3 u |
11 u |
The number of pears at first and in the end remains unchanged.
Number of pomegranates added
= 11 u - 7 u
= 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Number of less pears than pomegranates in the end
= 11 u - 3 u
= 8 u
= 8 x 4
= 32
Answer(s): 32
