The number of dates Charlie bought in May was 25% more than in April. In June, he bought 70% less dates than in May. If there were 45 more dates in April than June, how many dates did Charlie buy in April?
| April |
May |

| 4x2 |
5x2 |

10x1 |
3x1 |
| 8 u |
10 u |
3 u |
100% + 25 = 125%
125% =
125100 =
54May : April = 5 : 4
100% - 70% = 30%
30% =
30100 =
310 June : May = 3 : 10
The number of dates in May is repeated. Make the number of dates in May is the same. LCM of 5 and 10 is 10.
Number of more dates in April than June
= 8 u - 3 u
= 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Number of dates that Charlie bought in April
= 8 u
= 8 x 9
= 72
Answer(s): 72
