Solution

Z

Explanation:

First we will arrange the given information as  shown below:   
has 2 chessboards + 1 record player   
 Cost = 2 × 500 + 1 × 2000   
= 3000 (at the beginning)   
After transaction he has only 1 cycle and 1 chessboard   
 Total Cost = 1000 + 500 = 1500   
So, loss of X = 1500   
Z has 1 cycle + 1 walkman   
 Cost = 1000 + 700 = 1700     (at the beginning)   
After transaction he has only 1 bat and 1 chessboard and 1  camera 
 Total cost = 1 bat + 1 chessboard + 1 camera = 700 + 500  + 1500 = 2700   
 Profit = 1000   
Y has 3 bats   
∴ Total cost = 3 × 700 = 2100 (at the beginning)   
After transaction he has only 1 record player and 1 bat   
 Total cost = 2000 + 700 = 2700   
 Profit of Y = 600   
W has 2 cameras   
Cost = 5000 (at the beginning)   
After transaction he has only 1 bat, 1 camera and 1 walkman   
 Total cost = 1 bat + 1 camera + 1 Walkman   
= 700 + 3500 + 700 = 4900   
 Loss = 100 

Z became the highest gainer.
