There were some lemons and chikoos in Container C and Container D. In Container C, the ratio of the lemons to the number of chikoos was 7 : 1. In Container D, the ratio of the number of lemons to the number of chikoos was 5 : 3. There were 3 times as many fruits in Container C as in Container D. After another 119 chikoos were put into Container D, the ratio of the number of lemons to the number of chikoos in Container D became 1 : 4. How many fruits were there in Container D in the end?

Container C		Container D
3x8 = 24 u		1x8 = 8 u
Lemons	Chikoos	Lemons	Chikoos
7x3	1x3	5	3
21 u	3 u	5 u	3 u

The total number of fruits in Container C is repeated.  Make the total number of fruits in Container C the same.  LCM of 3 and 8 is 24.

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

	Container C		Container D
	Lemons	Chikoos	Lemons	Chikoos
Before	21 u	3 u	5 u	3 u
Change				+ 119
After	21 u	3 u	1x5 = 5 u	4x5 = 20 u

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

Number of chikoos put into Container D
= 20 u - 3 u
= 17 u

17 u = 119

1 u = 119 ÷ 17 = 7

Number of fruits in Container D in the end
= 5 u + 20 u
= 25 u
= 25 x 7
= 175

Answer(s): 175
