The number of kiwis Japheth bought in September was 25% more than in August. In October, he bought 50% less kiwis than in September. If there were 9 more kiwis in August than October, how many kiwis did Japheth buy in August?
| August |
September |
October |
| 4x2 |
5x2 |
|
| |
2x5 |
1x5 |
| 8 u |
10 u |
5 u |
100% + 25 = 125%
125% =
125100 =
54September : August = 5 : 4
100% - 50% = 50%
50% =
50100 =
12 October : September = 1 : 2
The number of kiwis in September is repeated. Make the number of kiwis in September is the same. LCM of 5 and 2 is 10.
Number of more kiwis in August than October
= 8 u - 5 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Number of kiwis that Japheth bought in August
= 8 u
= 8 x 3
= 24
Answer(s): 24
