The ratio of kiwis to persimmons is 3 : 4. If 36 persimmons are added, the ratio of kiwis to persimmons will be 3 : 8. How many less kiwis than persimmons are there in the end?
| |
Kiwis |
Persimmons |
| Before |
3 u |
4 u |
| Change |
|
+ 36 |
| After |
3 u |
8 u |
The number of kiwis at first and in the end remains unchanged.
Number of persimmons added
= 8 u - 4 u
= 4 u
4 u = 36
1 u = 36 ÷ 4 = 9
Number of less kiwis than persimmons in the end
= 8 u - 3 u
= 5 u
= 5 x 9
= 45
Answer(s): 45
