John and Ben shared some pens. John took
37 of the pens. After John lost 14 pens, Ben had four times as many pens as John. How many pens did Ben have in the end?

John |
Ben |
| Before |
3 u |
4 u |
| Change |
- 14 |
|
| After |
1x1 =
1 u |
4x1 =
4 u |
The number of pens that Ben had remains the same. Make the number of pens that Ben had the same. LCM of 4 and 4 is 4.
Number of pens that John lost
= 3 u - 1 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Number of pens that Ben had in the end
= 4 u
= 4 x 7
= 28
Answer(s): 28
