The number of plums Fred bought in August was 25% more than in July. In September, he bought 50% less plums than in August. If there were 24 less plums in September than July, how many plums did Fred buy in August?
| July |
August |
September |
| 4x2 |
5x2 |

2x5 |
1x5 |
| 8 u |
10 u |
5 u |
100% + 25 = 125%
125% =
125100 =
54August : July = 5 : 4
100% - 50% = 50%
50% =
50100 =
12 September : August = 1 : 2
The number of plums in August is repeated. Make the number of plums in August is the same. LCM of 5 and 2 is 10.
Number of less plums in September than July
= 8 u - 5 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Number of plums that Fred bought in August
= 10 u
= 10 x 8
= 80
Answer(s): 80
