The number of apricots Eric bought in March was 30% more than in February. In April, he bought 70% less apricots than in March. If there were 122 less apricots in April than February, how many apricots did Eric buy in March?

100% + 30 = 130%

1310March : February = 13 : 10
100% - 70% = 30%
30% =
30100 =
310 April : March = 3 : 10
The number of apricots in March is repeated. Make the number of apricots in March is the same. LCM of 13 and 10 is 130.
Number of less apricots in April than February
= 100 u - 39 u
= 61 u
61 u = 122
1 u = 122 ÷ 61 = 2
Number of apricots that Eric bought in March
= 130 u
= 130 x 2
= 260
Answer(s): 260
