The number of pears Flynn bought in October was 25% more than in September. In November, he bought 75% less pears than in October. If there were 66 more pears in September than November, how many pears did Flynn buy in September?
| September |
October |

| 4x4 |
5x4 |

4x5 |
1x5 |
| 16 u |
20 u |
5 u |
100% + 25 = 125%
125% =
125100 =
54October : September = 5 : 4
100% - 75% = 25%
25% =
25100 =
14 November : October = 1 : 4
The number of pears in October is repeated. Make the number of pears in October is the same. LCM of 5 and 4 is 20.
Number of more pears in September than November
= 16 u - 5 u
= 11 u
11 u = 66
1 u = 66 ÷ 11 = 6
Number of pears that Flynn bought in September
= 16 u
= 16 x 6
= 96
Answer(s): 96
