The ratio of kiwis to grapefruits is 3 : 8. If 24 grapefruits are added, the ratio of kiwis to grapefruits will be 3 : 10. How many less kiwis than grapefruits are there in the end?
| |
Kiwis |
Grapefruits |
| Before |
3 u |
8 u |
| Change |
|
+ 24 |
| After |
3 u |
10 u |
The number of kiwis at first and in the end remains unchanged.
Number of grapefruits added
= 10 u - 8 u
= 2 u
2 u = 24
1 u = 24 ÷ 2 = 12
Number of less kiwis than grapefruits in the end
= 10 u - 3 u
= 7 u
= 7 x 12
= 84
Answer(s): 84
