Answer 1

The Correct Option is B

From the given passage, Z originally had: - A cycle = ₹ 1000
- A walkman = ₹ 700
Therefore, \[ \text{Total value of Z's materials} = ₹ 1000 + ₹ 700 = \boxed{₹ 1700} \]

Answer 2

Let's evaluate each person’s item values at the beginning: X: - Two chessboards @ ₹ 500 = ₹ 1000
- One record player (value not directly given but used in a later transaction for a cricket bat worth ₹ 700 and walkman worth ₹ 700). Let’s conservatively take value = ₹ 1400 approx.
Total = ₹ 2400 Y: - Three cricket bats = 3 × ₹ 700 = ₹ 2100 Z: - Already calculated = ₹ 1700 W: - Two cameras = ₹ 5000 Clearly, W had the costliest items.

Answer 3

From the initial data: - W and Z both got a cricket bat from Y. That means Y originally had 3 cricket bats and gave 1 each to W and Z. - X did not receive any bat in any of the exchanges mentioned. \[ \Rightarrow \text{X did not have a cricket bat at the end.} \]

Answer 4

Z started with:
Cycle = ₹ 1000
Walkman = ₹ 700
Total = ₹ 1700 Final possessions: - Got a cricket bat = ₹ 700
- Got a chessboard from X = ₹ 500
- Got a camera from W = ₹ 1500
Total = ₹ 2700 Loss: walkman = ₹ 700, cycle = ₹ 1000 → total loss = ₹ 1700
Gain = ₹ 2700 - ₹ 1700 = \boxed{₹ 1000} Other individuals didn’t gain as much.

Answer 5

Let's check net losses: X: Gave away: 1 record player (₹ 1400), 1 chessboard (₹ 500) = ₹ 1900
Received: cricket bat (₹ 700), cycle (₹ 1000) → total = ₹ 1700 Net loss = ₹ 200 Y: Gave: 2 cricket bats = ₹ 1400
Received: record player = ₹ 1400
Net = 0 W: Gave camera = ₹ 1500
Received cricket bat = ₹ 700
Net loss = ₹ 800 Z: Gave walkman + cycle = ₹ 1700
Received: bat + camera + chessboard = ₹ 2700
Net gain = ₹ 1000 So none of the participants lost more than what they gave significantly, and no one had the highest "loss" that wasn't compensated.

Answer 6

We are to calculate total value of all remaining items after exchange among W, X, Y, Z. Final holdings include: - Cricket bats (3 people got from Y) = 3 × ₹ 700 = ₹ 2100
- Camera (Z received from W) = ₹ 1500
- Record player (Y received from X) = ₹ 2000
- Cycle (X got from Z) = ₹ 1000
- Walkman (W received from Z) = ₹ 700
- Chessboard (Z received from X) = ₹ 500
- X still has 1 chessboard = ₹ 500 \[ \text{Total} = 2100 + 1500 + 2000 + 1000 + 700 + 500 + 500 = ₹ 10300 \] So the range is between ₹ 10000 and ₹ 11000.

Answer 7

W received a walkman (₹ 700) and kept 2 cameras worth ₹ 5000 at the start. He gave 1 camera to Z. Therefore, W still holds one camera worth ₹ 2500.
That is the highest individual item retained after all exchanges. \[ \Rightarrow \text{W retained a camera worth } ₹ 2500. \]

Answer 8

Z had a cycle worth ₹ 1000. He gave it to X in exchange for a chessboard worth ₹ 500. So: \[ \text{Cycle (₹ 1000) was exchanged for chessboard (₹ 500)} \Rightarrow \text{loss of 50%} \] Now look at Y’s record player: - Gave record player (₹ 1400) and got a camera (₹ 1500) → Gain of ₹ 100 → ~7% gain. Camera: exchanged around its fair value. Cricket bat: Same value, all exchanged at ₹ 700. So the largest change in relative exchange rate in percentage occurred in the cycle.
