The number of mandarin oranges Luis bought in May was 20% more than in April. In June, he bought 60% less mandarin oranges than in May. If there were 91 less mandarin oranges in June than April, how many mandarin oranges did Luis buy in May?
| April |
May |
June |
| 5x5 |
6x5 |

5x6 |
2x6 |
| 25 u |
30 u |
12 u |
100% + 20 = 120%
120% =
120100 =
65May : April = 6 : 5
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 6 and 5 is 30.
Number of less mandarin oranges in June than April
= 25 u - 12 u
= 13 u
13 u = 91
1 u = 91 ÷ 13 = 7
Number of mandarin oranges that Luis bought in May
= 30 u
= 30 x 7
= 210
Answer(s): 210
