Profit and Loss

(21) A mobile phone was purchased for Rs. 12,000 and sold at a profit of 25%. What was the selling price of the mobile phone?

• (a) Rs. 13,000
• (b) Rs. 15,000
• (c) Rs. 15,000
• (d) Rs. 14,000

Answer

Correct Answer: (c) Rs. 15,000
The selling price (S.P.) can be calculated using the formula S.P. = C.P. \times (1 + \frac{Profit\%}{100}) . So, S.P. = 12000 \times (1 + \frac{25}{100}) = 12000 \times 1.25 = Rs. 15,000 .

(22) A bookstore marked the price of a novel at Rs. 350 and offered a 10% discount on it. If a customer bought the novel, what was the amount paid by the customer after the discount?

• (a) Rs. 300
• (b) Rs. 310
• (c) Rs. 315
• (d) Rs. 330

Answer

Correct Answer: (c) Rs. 315
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} = 350 \times (1 - \frac{10}{100}) = 350 \times 0.90 = Rs. 315 .

(23) A shopkeeper sold 60 toys at a profit of 18% each. If the cost price of each toy is Rs. 120, what was the total profit made on all toys?

• (a) Rs. 1296
• (b) Rs. 1296
• (c) Rs. 216
• (d) Rs. 1080

Answer

Correct Answer: (b) Rs. 1296
The profit made on each toy is Profit\text{ per toy} = C.P. \times \frac{Profit\%}{100} = 120 \times \frac{18}{100} = Rs. 21.60 . Therefore, the total profit on 60 toys is Total\text{ profit} = 60 \times 21.60 = Rs. 1296 .

(24) A company bought 200 chairs for Rs. 40,000 and sold them at Rs. 250 each. What was the percentage profit earned on each chair?

• (a) 12.5%
• (b) 25%
• (c) 20%
• (d) 15%

Answer

Correct Answer: (b) 25%
The percentage profit per chair can be calculated using the formula Profit\% = \frac{Profit}{C.P.} \times 100 . Each chair made a profit of Rs. 250 – Rs. 120 = Rs. 130, and the cost price (C.P.) of each chair was Rs. 120. Therefore, Profit\% = \frac{130}{120} \times 100 = \frac{13}{12} \times 100 = 25\% .

(25) A laptop was purchased for Rs. 45,000 and sold at a loss of 8%. What was the selling price of the laptop?

• (a) Rs. 41,400
• (b) Rs. 45,400
• (c) Rs. 48,600
• (d) Rs. 41,400

Answer

Correct Answer: (d) Rs. 41,400
The selling price (S.P.) can be calculated using the formula S.P. = C.P. \times (1 - \frac{Loss\%}{100}) . So, S.P. = 45000 \times (1 - \frac{8}{100}) = 45000 \times 0.92 = Rs. 41,400 .
