Yoko's mass compared to Warren's mass in percent
= 100% + 40%
= 140%
Hilda's mass compared to Warren's mass in percent
= 100% - 25%
= 75%

1520Warren's mass is the repeated identity. Make Warren's mass the same.
Warren's mass = 20 u
Mass that Yoko has more than Hilda
= 28 u - 15 u
= 13 u
13 u = 26
1 u = 26 ÷ 13 = 2
Warren's mass
= 20 u
= 20 x 2
= 40 kg
