Explanation:

To determine the loss or gain percentage, follow these steps:

- The selling price is Rs2,300 and the profit percentage is 25%. To find the cost price, use the formula: Cost Price = Selling Price / (1 + Profit Percentage).

- Cost Price = Rs2,300 / 1.25 = Rs1,840. This means the article was originally bought for Rs1,840.

- The article is sold again for Rs1,656. Calculate the difference: Loss = Cost Price - New Selling Price = Rs1,840 - Rs1,656 = Rs184.

- To find the loss percentage, use: Loss Percentage = (Loss / Cost Price) x 100 = (Rs184 / Rs1,840) x 100 ˜ 10%.

- Loss 10% Option 1 is correct.

- Option 2 (Gain 6.25%), Option 3 (Loss 6.5%), Option 4 (Gain 10%) are incorrect.
