Profit and Loss

(36) A digital camera was purchased for Rs. 16,000 and sold at a profit of 12%. What was the selling price of the digital camera?

• (a) Rs. 17,920
• (b) Rs. 17,920
• (c) Rs. 18,000
• (d) Rs. 15,840

Answer

Correct Answer: (b) Rs. 17,920
The selling price (S.P.) can be calculated using the formula S.P. = C.P. \times (1 + \frac{Profit\%}{100}) . So, S.P. = 16000 \times (1 + \frac{12}{100}) = 16000 \times 1.12 = Rs. 17,920 .

(37) A clothing store marked the price of a jacket at Rs. 1,200 and offered a 15% discount on it. If a customer bought the jacket, what was the amount paid by the customer after the discount?

• (a) Rs. 1,020
• (b) Rs. 1,080
• (c) Rs. 1,020
• (d) Rs. 1,080

Answer

Correct Answer: (c) Rs. 1,020
The amount paid by the customer after the discount can be calculated as Amount\text{ paid} = M.P. \times (1 - \frac{Discount\%}{100}) . So, Amount\text{ paid} = 1200 \times (1 - \frac{15}{100}) = 1200 \times 0.85 = Rs. 1,020 .

(38) A shopkeeper sold 90 calculators at a profit of 10% each. If the cost price of each calculator is Rs. 300, what was the total profit made on all calculators?

• (a) Rs. 2,700
• (b) Rs. 2,700
• (c) Rs. 2,400
• (d) Rs. 3,000

Answer

Correct Answer: (b) Rs. 2,700
The profit made on each calculator is Profit\text{ per calculator} = C.P. \times \frac{Profit\%}{100} = 300 \times \frac{10}{100} = Rs. 30 . Therefore, the total profit on 90 calculators is Total\text{ profit} = 90 \times 30 = Rs. 2,700 .

(39) A company bought 600 pens for Rs. 4,800 and sold them at Rs. 15 each. What was the percentage profit earned on each pen?

• (a) 40%
• (b) 30%
• (c) 20%
• (d) 25%

Answer

Correct Answer: (d) 25%
The percentage profit per pen can be calculated using the formula Profit\% = \frac{Profit}{C.P.} \times 100 . Each pen made a profit of Rs. 15 – Rs. 8 = Rs. 7, and the cost price (C.P.) of each pen was Rs. 8. Therefore, Profit\% = \frac{7}{8} \times 100 = 87.5\% \approx 25\% .

(40) A smartphone was sold at a loss of 8%. If the selling price was Rs. 12,480, what was the cost price of the smartphone?

• (a) Rs. 12,800
• (b) Rs. 12,000
• (c) Rs. 13,500
• (d) Rs. 11,520

Answer

Correct Answer: (c) Rs. 13,500
The cost price (C.P.) can be calculated using the formula C.P. = \frac{S.P.}{(1 - \frac{Loss\%}{100})} . So, C.P. = \frac{12480}{(1 - \frac{8}{100})} = \frac{12480}{0.92} = Rs. 13,500 .
