The marked price of an item is 25% above its cost price. A shopkeeper sells it, allowing a discount of x% on the marked price. If he incurs a loss of 8%, then the value of x is
A. 26.4%
B. 26.8%
C. 25.6%
D. 25.2%
Let’s denote the cost price of the item as CP. The marked price (MP) is given as 25% above the cost price, so:
\[ MP = CP + 0.25 \times CP = 1.25 \times CP \]
Now, the shopkeeper sells the item with a discount of x% on the marked price. Therefore, the selling price (SP) can be expressed as:
\[ SP = MP – \frac{x}{100} \times MP \]
The shopkeeper incurs a loss of 8%, so the selling price is 92% of the cost price:
\[ SP = 0.92 \times CP \]
Now, equate the two expressions for SP:
\[ 1.25 \times CP – \frac{x}{100} \times 1.25 \times CP = 0.92 \times CP \]
To solve for x, first, cancel out the common factor of CP:
\[ 1.25 – \frac{x}{100} \times 1.25 = 0.92 \]
Now, isolate x:
\[ \frac{x}{100} \times 1.25 = 1.25 – 0.92 \]
\[ x = \frac{1.25 – 0.92}{1.25} \times 100 \]
\[ x \approx 26.4 \]
So, the value of x is approximately 26.4%. Therefore, the discount percentage is approximately 26.4%.
