The number of grapefruits Billy bought in April was 40% more than in March. In May, he bought 60% less grapefruits than in April. If there were 132 more grapefruits in March than May, how many grapefruits did Billy buy in March?

75April : March = 7 : 5
100% - 60% = 40%
40% =
40100 =
25 May : April = 2 : 5
The number of grapefruits in April is repeated. Make the number of grapefruits in April is the same. LCM of 7 and 5 is 35.
Number of more grapefruits in March than May
= 25 u - 14 u
= 11 u
11 u = 132
1 u = 132 ÷ 11 = 12
Number of grapefruits that Billy bought in March
= 25 u
= 25 x 12
= 300
Answer(s): 300
