The number of coconuts Julian bought in October was 40% more than in September. In November, he bought 60% less coconuts than in October. If there were 44 less coconuts in November than September, how many coconuts did Julian buy in October?
| September |

5x7 |

| 25 u |
35 u |
14 u |
100% + 40 = 140%

75October : September = 7 : 5
100% - 60% = 40%
40% =
40100 =
25 November : October = 2 : 5
The number of coconuts in October is repeated. Make the number of coconuts in October is the same. LCM of 7 and 5 is 35.
Number of less coconuts in November than September
= 25 u - 14 u
= 11 u
11 u = 44
1 u = 44 ÷ 11 = 4
Number of coconuts that Julian bought in October
= 35 u
= 35 x 4
= 140
Answer(s): 140
