The number of mangosteens Brandon bought in May was 40% more than in April. In June, he bought 50% less mangosteens than in May. If there were 12 more mangosteens in April than June, how many mangosteens did Brandon buy in April?

14 u |

100% + 40 = 140%

75May : April = 7 : 5
100% - 50% = 50%
50% =
50100 =
12 June : May = 1 : 2
The number of mangosteens in May is repeated. Make the number of mangosteens in May is the same. LCM of 7 and 2 is 14.
Number of more mangosteens in April than June
= 10 u - 7 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of mangosteens that Brandon bought in April
= 10 u
= 10 x 4
= 40
Answer(s): 40
