Kylie's mass compared to Oscar's mass in percent
= 100% + 50%
= 150%
Min's mass compared to Oscar's mass in percent
= 100% - 30%
= 70%

710Oscar's mass is the repeated identity. Make Oscar's mass the same.
Oscar's mass = 10 u
Mass that Kylie has more than Min
= 15 u - 7 u
= 8 u
8 u = 56
1 u = 56 ÷ 8 = 7
Oscar's mass
= 10 u
= 10 x 7
= 70 kg
Answer(s): 70 kg
