The number of mandarin oranges Lee bought in May was 10% more than in April. In June, he bought 60% less mandarin oranges than in May. If there were 252 more mandarin oranges in April than June, how many mandarin oranges did Lee buy in April?

100% + 10 = 110%

1110May : April = 11 : 10
100% - 60% = 40%
40% =
40100 =
25 June : May = 2 : 5
The number of mandarin oranges in May is repeated. Make the number of mandarin oranges in May is the same. LCM of 11 and 5 is 55.
Number of more mandarin oranges in April than June
= 50 u - 22 u
= 28 u
28 u = 252
1 u = 252 ÷ 28 = 9
Number of mandarin oranges that Lee bought in April
= 50 u
= 50 x 9
= 450
Answer(s): 450
