Let the weight of Mark be x kg.
Therefore, Chen's weight is 2x kg.
Bob's weight is x/2 kg.
The total weight of Mark, Chen, and Bob is x + 2x + x/2 = 147 kg.
Combining like terms, we get 5x/2 = 147 kg.
Multiplying both sides by 2/5, we get x = (2/5) * 147 = 58.8 kg
Hence, Chen's weight is 2 * 58.8 = 117.6 kg. Answer: \boxed{117.6}.
The total weight of Bob, Chen, and Mark is 147kg. Chen is twice as heavy as Mark, and Bob’s weight is half of Mark’s weight. What is Chen’s weight?
