There were some passion fruits and chikoos in Container K and Container L. In Container K, the ratio of the passion fruits to the number of chikoos was 6 : 1. In Container L, the ratio of the number of passion fruits to the number of chikoos was 5 : 2. There were 2 times as many fruits in Container K as in Container L. After another 180 chikoos were put into Container L, the ratio of the number of passion fruits to the number of chikoos in Container L became 1 : 4. How many fruits were there in Container K?

Container K		Container L
2x7 = 14 u		1x7 = 7 u
Passion fruits	Chikoos	Passion fruits	Chikoos
6x2	1x2	5	2
12 u	2 u	5 u	2 u

The total number of fruits in Container K is repeated.  Make the total number of fruits in Container K the same.  LCM of 2 and 7 is 14.

The total number of fruits in Container L at first is repeated.  Make the total number of fruits in Container L the same.  LCM of 1 and 7 is 7.

	Container K		Container L
	Passion fruits	Chikoos	Passion fruits	Chikoos
Before	12 u	2 u	5 u	2 u
Change				+ 180
After	12 u	2 u	1x5 = 5 u	4x5 = 20 u

Number of passion fruits in Container L remains unchanged.  Make the number of passion fruits in Container L the same.  LCM of 5 and 1 is 5.

Number of chikoos put into Container L
= 20 u - 2 u
= 18 u

18 u = 180

1 u = 180 ÷ 18 = 10

Number of fruits in Container K
= 12 u + 2 u
= 14 u
= 14 x 10
= 140

Answer(s): 140
