The number of dragon fruits Rael bought in July was 40% more than in June. In August, he bought 75% less dragon fruits than in July. If there were 39 less dragon fruits in August than June, how many dragon fruits did Rael buy in July?

100% + 40 = 140%

75July : June = 7 : 5
100% - 75% = 25%
25% =
25100 =
14 August : July = 1 : 4
The number of dragon fruits in July is repeated. Make the number of dragon fruits in July is the same. LCM of 7 and 4 is 28.
Number of less dragon fruits in August than June
= 20 u - 7 u
= 13 u
13 u = 39
1 u = 39 ÷ 13 = 3
Number of dragon fruits that Rael bought in July
= 28 u
= 28 x 3
= 84
Answer(s): 84
