The number of lemons Perry bought in June was 40% more than in May. In July, he bought 60% less lemons than in June. If there were 121 less lemons in July than May, how many lemons did Perry buy in June?

100% + 40 = 140%

75June : May = 7 : 5
100% - 60% = 40%
40% =
40100 =
25 July : June = 2 : 5
The number of lemons in June is repeated. Make the number of lemons in June is the same. LCM of 7 and 5 is 35.
Number of less lemons in July than May
= 25 u - 14 u
= 11 u
11 u = 121
1 u = 121 ÷ 11 = 11
Number of lemons that Perry bought in June
= 35 u
= 35 x 11
= 385
Answer(s): 385
