The number of grapefruits Perry bought in June was 25% more than in May. In July, he bought 70% less grapefruits than in June. If there were 55 less grapefruits in July than May, how many grapefruits did Perry buy in June?
| May |
June |
July |
| 4x2 |
5x2 |

10x1 |
3x1 |
| 8 u |
10 u |
3 u |
100% + 25 = 125%
125% =
125100 =
54June : May = 5 : 4
100% - 70% = 30%
30% =
30100 =
310 July : June = 3 : 10
The number of grapefruits in June is repeated. Make the number of grapefruits in June is the same. LCM of 5 and 10 is 10.
Number of less grapefruits in July than May
= 8 u - 3 u
= 5 u
5 u = 55
1 u = 55 ÷ 5 = 11
Number of grapefruits that Perry bought in June
= 10 u
= 10 x 11
= 110
Answer(s): 110
