Question

David weighs 5 kg less than John, who in turn is 8 kg lighter than Paul. If their total weight is 197 kg, how heavy is each person ?​

Answer 1

Answer:

David 59.67 kg.

John 64.67 kg.

Paul 72.67 kg.

Step-by-step explanation:

Let Paul's weight be x kg.

Then:

x + x - 8 + x -  8 - 5 = 197

3x - 21 = 197

3x = 218

x = 72.67 kg.
