The number of coconuts Ivan bought in September was 40% more than in August. In October, he bought 50% less coconuts than in September. If there were 33 less coconuts in October than August, how many coconuts did Ivan buy in September?
| August |

| 10 u |
14 u |
7 u |
100% + 40 = 140%
140% =
140100 =
75September : August = 7 : 5
100% - 50% = 50%
50% =
50100 =
12 October : September = 1 : 2
The number of coconuts in September is repeated. Make the number of coconuts in September is the same. LCM of 7 and 2 is 14.
Number of less coconuts in October than August
= 10 u - 7 u
= 3 u
3 u = 33
1 u = 33 ÷ 3 = 11
Number of coconuts that Ivan bought in September
= 14 u
= 14 x 11
= 154
Answer(s): 154
