The number of grapefruits Luis bought in July was 25% more than in June. In August, he bought 70% less grapefruits than in July. If there were 25 less grapefruits in August than June, how many grapefruits did Luis buy in July?
| June |
July |

| 4x2 |
5x2 |

10x1 |
3x1 |
| 8 u |
10 u |
3 u |
100% + 25 = 125%
125% =
125100 =
54July : June = 5 : 4
100% - 70% = 30%
30% =
30100 =
310 August : July = 3 : 10
The number of grapefruits in July is repeated. Make the number of grapefruits in July is the same. LCM of 5 and 10 is 10.
Number of less grapefruits in August than June
= 8 u - 3 u
= 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Number of grapefruits that Luis bought in July
= 10 u
= 10 x 5
= 50
Answer(s): 50
