There were some pens in Bag L and Bag M. After Nick transferred
14 of the pens from Bag L to Bag M, the ratio of the number of pens in Bag L to that in Bag M changed to 2 : 3. Find the ratio of the numbers of pens in Bag M to the number of pens in Bag L at first.
|
Bag L |
Bag M |
Before |
4x2 = 8 u |
7 u |
Change |
- 1x2 = - 2 u |
+ 2 u |
After |
3x2 = 6 u |
|
Comparing Bag L and Bag M in the end |
2x3 = 6 u |
3x3 = 9 u |
The number of pens in Bag L in the end is repeated. Make the number of pens in Bag L in the end the same. LCM of 3 and 2 is 6.
At first
Bag M : Bag L
7: 8
Answer(s): 7: 8
