The number of peaches Henry bought in February was 20% more than in January. In March, he bought 75% less peaches than in February. If there were 21 more peaches in January than March, how many peaches did Henry buy in January?
| January |
February |
March |
| 5x2 |
6x2 |

4x3 |
1x3 |
| 10 u |
12 u |
3 u |
100% + 20 = 120%
120% =
120100 =
65February : January = 6 : 5
100% - 75% = 25%
25% =
25100 =
14 March : February = 1 : 4
The number of peaches in February is repeated. Make the number of peaches in February is the same. LCM of 6 and 4 is 12.
Number of more peaches in January than March
= 10 u - 3 u
= 7 u
7 u = 21
1 u = 21 ÷ 7 = 3
Number of peaches that Henry bought in January
= 10 u
= 10 x 3
= 30
Answer(s): 30
