The number of apples Seth bought in May was 40% more than in April. In June, he bought 75% less apples than in May. If there were 91 more apples in April than June, how many apples did Seth buy in April?

100% + 40 = 140%

75May : April = 7 : 5
100% - 75% = 25%
25% =
25100 =
14 June : May = 1 : 4
The number of apples in May is repeated. Make the number of apples in May is the same. LCM of 7 and 4 is 28.
Number of more apples in April than June
= 20 u - 7 u
= 13 u
13 u = 91
1 u = 91 ÷ 13 = 7
Number of apples that Seth bought in April
= 20 u
= 20 x 7
= 140
Answer(s): 140
