Lynn's mass compared to Owen's mass in percent
= 100% + 40%
= 140%
Zoe's mass compared to Owen's mass in percent
= 100% - 50%
= 50%

510Owen's mass is the repeated identity. Make Owen's mass the same.
Owen's mass = 10 u
Mass that Lynn has more than Zoe
= 14 u - 5 u
= 9 u
9 u = 54
1 u = 54 ÷ 9 = 6
Owen's mass
= 10 u
= 10 x 6
= 60 kg
Answer(s): 60 kg
