#### Options

Rs 1500

Rs. 1700

Rs 1000

Rs. 2000

#### Solution

**Rs. 1700**

**Explanation:**

First we will arrange the given information as shown below:

X 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
