100% - 75% = 25%

14 August : July = 1 : 4
The number of plums in July is repeated. Make the number of plums in July is the same. LCM of 13 and 4 is 52.
Number of more plums in June than August
= 40 u - 13 u
= 27 u
27 u = 216
1 u = 216 ÷ 27 = 8
Number of plums that Simon bought in June
= 40 u
= 40 x 8
= 320
Answer(s): 320
