14 August : July = 1 : 4
The number of pomegranates in July is repeated. Make the number of pomegranates in July is the same. LCM of 13 and 4 is 52.
Number of less pomegranates in August than June
= 40 u - 13 u
= 27 u
27 u = 324
1 u = 324 ÷ 27 = 12
Number of pomegranates that Elijah bought in July
= 52 u
= 52 x 12
= 624
Answer(s): 624
