The number of grapefruits Japheth bought in February was 40% more than in January. In March, he bought 60% less grapefruits than in February. If there were 110 more grapefruits in January than March, how many grapefruits did Japheth buy in January?
| January |
February |
March |
| 5x5 |
7x5 |

5x7 |
2x7 |
| 25 u |
35 u |
14 u |
100% + 40 = 140%
140% =
140100 =
75February : January = 7 : 5
100% - 60% = 40%
40% =
40100 =
25 March : February = 2 : 5
The number of grapefruits in February is repeated. Make the number of grapefruits in February is the same. LCM of 7 and 5 is 35.
Number of more grapefruits in January than March
= 25 u - 14 u
= 11 u
11 u = 110
1 u = 110 ÷ 11 = 10
Number of grapefruits that Japheth bought in January
= 25 u
= 25 x 10
= 250
Answer(s): 250
