Q.The cost price of a bag is ₹250. It is sold at a loss of 8%. Find the selling price.

A loss of 8% makes the selling price 92% of the cost price.

$SP=250\times(1-0.08)=250\times0.92=₹230$.

Here $CP=₹250$ and the loss is $8\%$ of the cost price.

Step 1 — Apply the selling-price formula for a loss.

Step 2 — Evaluate.

Check (independent verification). Loss $=250-230=₹20$ and $\dfrac{20}{250}\times100=8\%$, matching the stated loss.

Adding the loss instead of subtracting it (getting ₹270) reverses the sense of a loss. A loss always makes the selling price smaller than the cost price.
