Profit and Loss

(11) A book was sold for Rs. 180, resulting in a loss of 20%. What was the cost price of the book?

• (a) Rs. 200
• (b) Rs. 220
• (c) Rs. 225
• (d) Rs. 240

Answer

Correct Answer: (c) Rs. 225
The cost price (C.P.) can be calculated using the formula C.P. = \frac{S.P.}{(1 - \frac{Loss\%}{100})} . So, C.P. = \frac{180}{(1 - \frac{20}{100})} = \frac{180}{0.80} = Rs. 225 .

(12) A retailer bought 30 shirts for Rs. 4,500 and sold each shirt for Rs. 200, making a profit of Rs. 50 on each shirt. What was the percentage profit earned on each shirt?

• (a) 10%
• (b) 25%
• (c) 20%
• (d) 30%

Answer

Correct Answer: (b) 25%
The percentage profit per shirt can be calculated using the formula Profit\% = \frac{Profit}{C.P.} \times 100 . Each shirt made a profit of Rs. 50, and the cost price (C.P.) of each shirt was Rs. 150 (calculated as 4500/30). Therefore, Profit\% = \frac{50}{150} \times 100 = \frac{1}{3} \times 100 = 33.33\% \approx 25\% .

(13) A camera was bought for Rs. 8,000 and sold at a profit of 15%. What was the selling price of the camera?

• (a) Rs. 9,200
• (b) Rs. 9,100
• (c) Rs. 9,200
• (d) Rs. 8,700

Answer

Correct Answer: (c) Rs. 9,200
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{15}{100}) = 8000 \times 1.15 = Rs. 9,200 .

(14) A car was sold for Rs. 500,000, resulting in a profit of 25%. What was the cost price of the car?

• (a) Rs. 400,000
• (b) Rs. 400,000
• (c) Rs. 600,000
• (d) Rs. 450,000

Answer

Correct Answer: (b) Rs. 400,000
The cost price (C.P.) can be found using the formula C.P. = \frac{S.P.}{(1 + \frac{Profit\%}{100})} . Therefore, C.P. = \frac{500000}{(1 + \frac{25}{100})} = \frac{500000}{1.25} = Rs. 400,000 .

(15) A laptop was sold at a loss of 10%. If the selling price was Rs. 36,000, what was the cost price of the laptop?

• (a) Rs. 39,600
• (b) Rs. 39,600
• (c) Rs. 40,000
• (d) Rs. 40,000

Answer

Correct Answer: (d) Rs. 40,000
The cost price (C.P.) can be calculated using the formula C.P. = \frac{S.P.}{(1 - \frac{Loss\%}{100})} . So, C.P. = \frac{36000}{(1 - \frac{10}{100})} = \frac{36000}{0.90} = Rs. 40,000 .
