The number of mangosteens Lee bought in June was 20% more than in May. In July, he bought 70% less mangosteens than in June. If there were 112 less mangosteens in July than May, how many mangosteens did Lee buy in June?

30 u |

100% + 20 = 120%

65June : May = 6 : 5
100% - 70% = 30%
30% =
30100 =
310 July : June = 3 : 10
The number of mangosteens in June is repeated. Make the number of mangosteens in June is the same. LCM of 6 and 10 is 30.
Number of less mangosteens in July than May
= 25 u - 9 u
= 16 u
16 u = 112
1 u = 112 ÷ 16 = 7
Number of mangosteens that Lee bought in June
= 30 u
= 30 x 7
= 210
Answer(s): 210
