The ratio of peaches to starfruits is 3 : 8. If 27 starfruits are added, the ratio of peaches to starfruits will be 3 : 11. How many more starfruits than peaches are there in the end?
| |
Peaches |
Starfruits |
| Before |
3 u |
8 u |
| Change |
|
+ 27 |
| After |
3 u |
11 u |
The number of peaches at first and in the end remains unchanged.
Number of starfruits added
= 11 u - 8 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Number of more starfruits than peaches in the end
= 11 u - 3 u
= 8 u
= 8 x 9
= 72
Answer(s): 72
