A, B and C weigh 51 kg, B and C weigh 53 kg, a and C weigh 52 kg, how many kg are they?

A, B and C weigh 51 kg, B and C weigh 53 kg, a and C weigh 52 kg, how many kg are they?

A (51 + 52-53) / 2 = 25 B 51-25 = 26 C 53-26 = 27

2. The average weight of a, B and C is 53 kg. The average weight of a and B is 51.5 kg. A is 5 kg heavier than B. how many kg does a, B and C weigh?

C: 53x3-51.5x2 = 56kg
A: (51.5x2 + 5) △ 2 = 54kg
B: 54-5 = 49kg

A, B and C three people weight, a and B total weight of 51 kg. A and C total weight of 53 kg, a and C total weight of 52 kg?

(51+53+52)/2=78(kg)
C: 78-51 = 27 (kg)
B: 53-27 = 26 (kg)
A: 51-26 = 25 (kg)

The average weight of dongheming is 48.5 kg, that of donghehua is 56 kg, and that of huaheming is 52.5 kg?

You can add up the three quantities
Got 157
It's the weight and weight of three people
For Xiaodong, 157-52.5 * 2 = 52kg is required
