The number of dragon fruits Fabian bought in August was 25% more than in July. In September, he bought 70% less dragon fruits than in August. If there were 40 less dragon fruits in September than July, how many dragon fruits did Fabian buy in August?
| July |
August |

| 4x2 |
5x2 |

10x1 |
3x1 |
| 8 u |
10 u |
3 u |
100% + 25 = 125%
125% =
125100 =
54August : July = 5 : 4
100% - 70% = 30%
30% =
30100 =
310 September : August = 3 : 10
The number of dragon fruits in August is repeated. Make the number of dragon fruits in August is the same. LCM of 5 and 10 is 10.
Number of less dragon fruits in September than July
= 8 u - 3 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of dragon fruits that Fabian bought in August
= 10 u
= 10 x 8
= 80
Answer(s): 80
