There were some coins in Bag N and Bag P. After Luke transferred
14 of the coins from Bag N to Bag P, the ratio of the number of coins in Bag N to that in Bag P changed to 1 : 8. Find the ratio of the numbers of coins in Bag P to the number of coins in Bag N at first.
|
Bag N |
Bag P |
Before |
4x1 = 4 u |
23 u |
Change |
- 1x1 = - 1 u |
+ 1 u |
After |
3x1 = 3 u |
|
Comparing Bag N and Bag P in the end |
1x3 = 3 u |
8x3 = 24 u |
The number of coins in Bag N in the end is repeated. Make the number of coins in Bag N in the end the same. LCM of 3 and 1 is 3.
At first
Bag P : Bag N
23: 4
Answer(s): 23: 4
