Yoko's mass compared to Valen's mass in percent
= 100% + 25%
= 125%
Irene's mass compared to Valen's mass in percent
= 100% - 50%
= 50%

24Valen's mass is the repeated identity. Make Valen's mass the same.
Valen's mass = 4 u
Mass that Yoko has more than Irene
= 5 u - 2 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Valen's mass
= 4 u
= 4 x 9
= 36 kg
Answer(s): 36 kg
