There were some starfruits and pomegranates in Container F and Container G. In Container F, the ratio of the starfruits to the number of pomegranates was 7 : 1. In Container G, the ratio of the number of starfruits to the number of pomegranates was 5 : 3. There were 2 times as many fruits in Container F as in Container G. After another 36 pomegranates were put into Container G, the ratio of the number of starfruits to the number of pomegranates in Container G became 1 : 3. How many fruits were there in Container F?

Container F		Container G
2x8 = 16 u		1x8 = 8 u
Starfruits	Pomegranates	Starfruits	Pomegranates
7x2	1x2	5	3
14 u	2 u	5 u	3 u

The total number of fruits in Container F is repeated.  Make the total number of fruits in Container F the same.  LCM of 2 and 8 is 16.

The total number of fruits in Container G at first is repeated.  Make the total number of fruits in Container G the same.  LCM of 1 and 8 is 8.

	Container F		Container G
	Starfruits	Pomegranates	Starfruits	Pomegranates
Before	14 u	2 u	5 u	3 u
Change				+ 36
After	14 u	2 u	1x5 = 5 u	3x5 = 15 u

Number of starfruits in Container G remains unchanged.  Make the number of starfruits in Container G the same.  LCM of 5 and 1 is 5.

Number of pomegranates put into Container G
= 15 u - 3 u
= 12 u

12 u = 36

1 u = 36 ÷ 12 = 3

Number of fruits in Container F
= 14 u + 2 u
= 16 u
= 16 x 3
= 48

Answer(s): 48
