The number of kiwis Lee bought in September was 10% more than in August. In October, he bought 75% less kiwis than in September. If there were 58 more kiwis in August than October, how many kiwis did Lee buy in August?

100% + 10 = 110%

1110September : August = 11 : 10
100% - 75% = 25%
25% =
25100 =
14 October : September = 1 : 4
The number of kiwis in September is repeated. Make the number of kiwis in September is the same. LCM of 11 and 4 is 44.
Number of more kiwis in August than October
= 40 u - 11 u
= 29 u
29 u = 58
1 u = 58 ÷ 29 = 2
Number of kiwis that Lee bought in August
= 40 u
= 40 x 2
= 80
Answer(s): 80
