The number of kiwis Sam bought in October was 40% more than in September. In November, he bought 50% less kiwis than in October. If there were 6 less kiwis in November than September, how many kiwis did Sam buy in October?
| September |
October |
November |
| 5x2 |
7x2 |

2x7 |
1x7 |
| 10 u |
14 u |
7 u |
100% + 40 = 140%
140% =
140100 =
75October : September = 7 : 5
100% - 50% = 50%
50% =
50100 =
12 November : October = 1 : 2
The number of kiwis in October is repeated. Make the number of kiwis in October is the same. LCM of 7 and 2 is 14.
Number of less kiwis in November than September
= 10 u - 7 u
= 3 u
3 u = 6
1 u = 6 ÷ 3 = 2
Number of kiwis that Sam bought in October
= 14 u
= 14 x 2
= 28
Answer(s): 28
