The number of mandarin oranges Rael bought in May was 30% more than in April. In June, he bought 75% less mandarin oranges than in May. If there were 108 less mandarin oranges in June than April, how many mandarin oranges did Rael buy in May?

100% + 30 = 130%

100% - 75% = 25%
25% =
25100 =
14 June : May = 1 : 4
The number of mandarin oranges in May is repeated. Make the number of mandarin oranges in May is the same. LCM of 13 and 4 is 52.
Number of less mandarin oranges in June than April
= 40 u - 13 u
= 27 u
27 u = 108
1 u = 108 ÷ 27 = 4
Number of mandarin oranges that Rael bought in May
= 52 u
= 52 x 4
= 208
Answer(s): 208
