The number of apricots Howard bought in July was 40% more than in June. In August, he bought 70% less apricots than in July. If there were 319 less apricots in August than June, how many apricots did Howard buy in July?

100% + 40 = 140%

75July : June = 7 : 5
100% - 70% = 30%
30% =
30100 =
310 August : July = 3 : 10
The number of apricots in July is repeated. Make the number of apricots in July is the same. LCM of 7 and 10 is 70.
Number of less apricots in August than June
= 50 u - 21 u
= 29 u
29 u = 319
1 u = 319 ÷ 29 = 11
Number of apricots that Howard bought in July
= 70 u
= 70 x 11
= 770
Answer(s): 770
