The number of apples Owen bought in August was 40% more than in July. In September, he bought 75% less apples than in August. If there were 52 more apples in July than September, how many apples did Owen buy in July?
| July |

| 20 u |
28 u |
7 u |
100% + 40 = 140%
140% =
140100 =
75August : July = 7 : 5
100% - 75% = 25%
25% =
25100 =
14 September : August = 1 : 4
The number of apples in August is repeated. Make the number of apples in August is the same. LCM of 7 and 4 is 28.
Number of more apples in July than September
= 20 u - 7 u
= 13 u
13 u = 52
1 u = 52 ÷ 13 = 4
Number of apples that Owen bought in July
= 20 u
= 20 x 4
= 80
Answer(s): 80
