Detailed Solution

It is given that the cost price of 10 chairs is equal to the sale price of 5 chairs.
Let’s suppose that the cost price of 1 chair = Rs10.
Therefore the cost price of 10 chairs =

Rs 10 × 10 = Rs 100.

It is given that the cost price of 10 chairs = the sale price of 5 chairs.
Therefore, the sale price of 5 chairs = Rs100.
Therefore profit = Rs100.

∴ Profit percentage = 100100 × 100 % ⇒ Profit percentage = 100 %

Thus, the percentage of profit in this transaction will be 100%.
Hence, option (4) is correct.
