There were some oranges and chikoos in Container L and Container M. In Container L, the ratio of the oranges to the number of chikoos was 2 : 1. In Container M, the ratio of the number of oranges to the number of chikoos was 3 : 1. There were 3 times as many fruits in Container L as in Container M. After another 72 chikoos were put into Container M, the ratio of the number of oranges to the number of chikoos in Container M became 1 : 3. How many fruits were there in Container M in the end?

The total number of fruits in Container L is repeated. Make the total number of fruits in Container L the same. LCM of 3 and 3 is 12.
The total number of fruits in Container M at first is repeated. Make the total number of fruits in Container M the same. LCM of 1 and 4 is 4.

Number of oranges in Container M remains unchanged. Make the number of oranges in Container M the same. LCM of 3 and 1 is 3.
Number of chikoos put into Container M
= 9 u - 1 u
= 8 u
8 u = 72
1 u = 72 ÷ 8 = 9
Number of fruits in Container M in the end
= 3 u + 9 u
= 12 u
= 12 x 9
= 108
Answer(s): 108
