Shiyun's mass compared to Owen's mass in percent
= 100% + 40%
= 140%
Barbara's mass compared to Owen's mass in percent
= 100% - 30%
= 70%

710Owen's mass is the repeated identity. Make Owen's mass the same.
Owen's mass = 10 u
Mass that Shiyun has more than Barbara
= 14 u - 7 u
= 7 u
7 u = 35
1 u = 35 ÷ 7 = 5
Owen's mass
= 10 u
= 10 x 5
= 50 kg
Answer(s): 50 kg
