The number of pears John bought in June was 25% more than in May. In July, he bought 70% less pears than in June. If there were 10 less pears in July than May, how many pears did John 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 pears in June is repeated. Make the number of pears in June is the same. LCM of 5 and 10 is 10.
Number of less pears in July than May
= 8 u - 3 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Number of pears that John bought in June
= 10 u
= 10 x 2
= 20
Answer(s): 20
