Profit and Loss

(31) A tablet was purchased for Rs. 8,000 and sold at a profit of 30%. What was the selling price of the tablet?

• (a) Rs. 10,000
• (b) Rs. 10,400
• (c) Rs. 9,600
• (d) Rs. 8,400

Answer

Correct Answer: (b) Rs. 10,400
The selling price (S.P.) can be calculated using the formula S.P. = C.P. \times (1 + \frac{Profit\%}{100}) . So, S.P. = 8000 \times (1 + \frac{30}{100}) = 8000 \times 1.30 = Rs. 10,400 .

(32) A bookstore marked the price of a novel at Rs. 280 and offered a 20% discount on it. If a customer bought the novel, what was the amount paid by the customer after the discount?

• (a) Rs. 240
• (b) Rs. 250
• (c) Rs. 224
• (d) Rs. 260

Answer

Correct Answer: (c) Rs. 224
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} = 280 \times (1 - \frac{20}{100}) = 280 \times 0.80 = Rs. 224 .

(33) A shopkeeper sold 75 watches at a profit of 15% each. If the cost price of each watch is Rs. 500, what was the total profit made on all watches?

• (a) Rs. 5,625
• (b) Rs. 5,625
• (c) Rs. 1,125
• (d) Rs. 4,500

Answer

Correct Answer: (b) Rs. 5,625
The profit made on each watch is Profit\text{ per watch} = C.P. \times \frac{Profit\%}{100} = 500 \times \frac{15}{100} = Rs. 75 . Therefore, the total profit on 75 watches is Total\text{ profit} = 75 \times 75 = Rs. 5,625 .

(34) A company bought 800 chairs for Rs. 48,000 and sold them at Rs. 75 each. What was the percentage profit earned on each chair?

• (a) 37.50%
• (b) 56.25%
• (c) 25%
• (d) 50%

Answer

Correct Answer: (b) 56.25%
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. 75 – Rs. 60 = Rs. 15, and the cost price (C.P.) of each chair was Rs. 60. Therefore, Profit\% = \frac{15}{60} \times 100 = \frac{1}{4} \times 100 = 25\% \times 2.25 = 56.25\% .

(35) A microwave was sold at a loss of 10%. If the selling price was Rs. 9,000, what was the cost price of the microwave?

• (a) Rs. 10,000
• (b) Rs. 10,000
• (c) Rs. 9,900
• (d) Rs. 9,800

Answer

Correct Answer: (b) Rs. 10,000
The cost price (C.P.) can be calculated using the formula C.P. = \frac{S.P.}{(1 - \frac{Loss\%}{100})} . So, C.P. = \frac{9000}{(1 - \frac{10}{100})} = \frac{9000}{0.90} = Rs. 10,000 .
