Profit and Loss

(41) A bicycle was purchased for Rs. 3,500 and sold at a profit of 25%. What was the selling price of the bicycle?

• (a) Rs. 4,000
• (b) Rs. 4,375
• (c) Rs. 3,750
• (d) Rs. 4,500

Answer

Correct Answer: (b) Rs. 4,375
The selling price (S.P.) can be calculated using the formula S.P. = C.P. \times (1 + \frac{Profit\%}{100}) . So, S.P. = 3500 \times (1 + \frac{25}{100}) = 3500 \times 1.25 = Rs. 4,375 .

(42) A toy store marked the price of a toy at Rs. 800 and offered a 10% discount on it. If a customer bought the toy, what was the amount paid by the customer after the discount?

• (a) Rs. 720
• (b) Rs. 720
• (c) Rs. 810
• (d) Rs. 880

Answer

Correct Answer: (b) Rs. 720
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} = 800 \times (1 - \frac{10}{100}) = 800 \times 0.90 = Rs. 720 .

(43) A shopkeeper sold 60 watches at a profit of 18% each. If the cost price of each watch is Rs. 400, what was the total profit made on all watches?

• (a) Rs. 3,240
• (b) Rs. 3,240
• (c) Rs. 3,600
• (d) Rs. 3,000

Answer

Correct Answer: (b) Rs. 3,240
The profit made on each watch is Profit\text{ per watch} = C.P. \times \frac{Profit\%}{100} = 400 \times \frac{18}{100} = Rs. 72 . Therefore, the total profit on 60 watches is Total\text{ profit} = 60 \times 72 = Rs. 3,240 .

(44) A company bought 450 pens for Rs. 5,850 and sold them at Rs. 18 each. What was the percentage profit earned on each pen?

• (a) 27.50%
• (b) 30%
• (c) 22.50%
• (d) 25%

Answer

Correct Answer: (c) 22.50%
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. 18 – Rs. 13 = Rs. 5, and the cost price (C.P.) of each pen was Rs. 13. Therefore, Profit\% = \frac{5}{13} \times 100 \approx 22.50\% .

(45) A laptop was sold at a loss of 15%. If the selling price was Rs. 42,500, what was the cost price of the laptop?

• (a) Rs. 48,000
• (b) Rs. 50,000
• (c) Rs. 45,000
• (d) Rs. 47,500

Answer

Correct Answer: (b) Rs. 50,000
The cost price (C.P.) can be calculated using the formula C.P. = \frac{S.P.}{(1 - \frac{Loss\%}{100})} . So, C.P. = \frac{42500}{(1 - \frac{15}{100})} = \frac{42500}{0.85} = Rs. 50,000 .
