There were some coins in Bag L and Bag M. After Wesley transferred
25 of the coins from Bag L to Bag M, the ratio of the number of coins in Bag L to that in Bag M changed to 2 : 5. Find the ratio of the numbers of coins in Bag L to the number of coins in Bag M at first.
|
Bag L |
Bag M |
Before |
5x2 = 10 u |
11 u |
Change |
- 2x2 = - 4 u |
+ 4 u |
After |
3x2 = 6 u |
|
Comparing Bag L and Bag M in the end |
2x3 = 6 u |
5x3 = 15 u |
The number of coins in Bag L in the end is repeated. Make the number of coins in Bag L in the end the same. LCM of 3 and 2 is 6.
At first
Bag L : Bag M
10 : 11
Answer(s): 10 : 11
