The number of pears Archie bought in September was 20% more than in August. In October, he bought 50% less pears than in September. If there were 24 less pears in October than August, how many pears did Archie buy in September?
| August |
September |

| 5x1 |
6x1 |

2x3 |
1x3 |
| 5 u |
6 u |
3 u |
100% + 20 = 120%
120% =
120100 =
65September : August = 6 : 5
100% - 50% = 50%
50% =
50100 =
12 October : September = 1 : 2
The number of pears in September is repeated. Make the number of pears in September is the same. LCM of 6 and 2 is 6.
Number of less pears in October than August
= 5 u - 3 u
= 2 u
2 u = 24
1 u = 24 ÷ 2 = 12
Number of pears that Archie bought in September
= 6 u
= 6 x 12
= 72
Answer(s): 72
