A man bought 400 meters of cloth for Rs. 40,000 & sold it at a rate of Rs. 200 per one and a half meter. What was his percentage profit or loss?

Sure, let's solve this step by step:

Step 1: Calculate the cost price per meter of cloth. The man bought 400 meters of cloth for Rs. 40,000. So, the cost price per meter is Rs. 40,000 / 400 = Rs. 100.

Step 2: Calculate the selling price per meter of cloth. He sold the cloth at a rate of Rs. 200 per one and a half meter. So, the selling price per meter is Rs. 200 / 1.5 = Rs. 133.33 (approximately).

Step 3: Calculate the profit or loss. The selling price per meter is Rs. 133.33 and the cost price per meter is Rs. 100. So, he made a profit of Rs. 133.33 - Rs. 100 = Rs. 33.33 per meter.

Step 4: Calculate the percentage profit. The percentage profit is (Profit per meter / Cost price per meter) * 100 = (Rs. 33.33 / Rs. 100) * 100 = 33.33%.

So, the man made a profit of 33.33% on the cloth.
