Wendy's mass compared to Henry's mass in percent
= 100% + 30%
= 130%
Jade's mass compared to Henry's mass in percent
= 100% - 50%
= 50%

510Henry's mass is the repeated identity. Make Henry's mass the same.
Henry's mass = 10 u
Mass that Wendy has more than Jade
= 13 u - 5 u
= 8 u
8 u = 24
1 u = 24 ÷ 8 = 3
Henry's mass
= 10 u
= 10 x 3
= 30 kg
Answer(s): 30 kg
