There were some coins in Bag B and Bag C. After Luis transferred
35 of the coins from Bag B to Bag C, the ratio of the number of coins in Bag B to that in Bag C changed to 1 : 8. Find the ratio of the numbers of coins in Bag C to the number of coins in Bag B at first.
|
Bag B |
Bag C |
Before |
5x1 = 5 u |
13 u |
Change |
- 3x1 = - 3 u |
+ 3 u |
After |
2x1 = 2 u |
|
Comparing Bag B and Bag C in the end |
1x2 = 2 u |
8x2 = 16 u |
The number of coins in Bag B in the end is repeated. Make the number of coins in Bag B in the end the same. LCM of 2 and 1 is 2.
At first
Bag C : Bag B
13: 5
Answer(s): 13: 5
