Opal's mass compared to Asher's mass in percent
= 100% + 50%
= 150%
Eva's mass compared to Asher's mass in percent
= 100% - 40%
= 60%

610Asher's mass is the repeated identity. Make Asher's mass the same.
Asher's mass = 10 u
Mass that Opal has more than Eva
= 15 u - 6 u
= 9 u
9 u = 45
1 u = 45 ÷ 9 = 5
Asher's mass
= 10 u
= 10 x 5
= 50 kg
Answer(s): 50 kg
