The number of plums John bought in April was 40% more than in March. In May, he bought 75% less plums than in April. If there were 52 less plums in May than March, how many plums did John buy in April?
| March |
April |

| 5x4 |
7x4 |

4x7 |
1x7 |
| 20 u |
28 u |
7 u |
100% + 40 = 140%
140% =
140100 =
75April : March = 7 : 5
100% - 75% = 25%
25% =
25100 =
14 May : April = 1 : 4
The number of plums in April is repeated. Make the number of plums in April is the same. LCM of 7 and 4 is 28.
Number of less plums in May than March
= 20 u - 7 u
= 13 u
13 u = 52
1 u = 52 ÷ 13 = 4
Number of plums that John bought in April
= 28 u
= 28 x 4
= 112
Answer(s): 112
