The number of coconuts Fred bought in July was 30% more than in June. In August, he bought 50% less coconuts than in July. If there were 28 more coconuts in June than August, how many coconuts did Fred buy in June?

100% - 50% = 50%

12 August : July = 1 : 2
The number of coconuts in July is repeated. Make the number of coconuts in July is the same. LCM of 13 and 2 is 26.
Number of more coconuts in June than August
= 20 u - 13 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Number of coconuts that Fred bought in June
= 20 u
= 20 x 4
= 80
Answer(s): 80
