2 u |

The amount that Andy had remains unchanged. Make the amount that Andy had the same. LCM of 1 and 2 is 2.
Amount that Mark had in the end = 1 u
16 u - 120 = 1 u
16 u - 1 u = 120
15 u = 120
1 u = 120 ÷ 15 = 8
Amount that Andy had more than Julian at first
= 16 u - 2 u
= 14 u
= 14 x 8
= $112
Answer(s): $112
