Hazel's mass compared to Julian's mass in percent
= 100% + 50%
= 150%
Marion's mass compared to Julian's mass in percent
= 100% - 30%
= 70%

710Julian's mass is the repeated identity. Make Julian's mass the same.
Julian's mass = 10 u
Mass that Hazel has more than Marion
= 15 u - 7 u
= 8 u
8 u = 48
1 u = 48 ÷ 8 = 6
Julian's mass
= 10 u
= 10 x 6
= 60 kg
Answer(s): 60 kg
