Option 1: 25%
Option 2: 30%
Option 3: 10%
Option 4: 20%
Correct Answer: 20%
Solution : Given: Rohit buys an old bat for Rs. 880 and spends Rs. 120 on its repair, he sells it for Rs. 800 The total cost of the bat (CP) = (880 + 120) = Rs. 1000 Selling price (SP) = Rs. 800 So, the loss
Question : A person bought some pens at the rate of 25 for a rupee and sold them at the rate of 20 for the rupee. What is the profit percentage?
Option 1: 30 percent
Option 2: 10 percent
Option 3: 25 percent
Option 4: 15 percent
Correct Answer: 25 percent
Solution : The cost of each pen (CP) = $\frac{1}{25}$ The selling price of each pen (SP) = $\frac{1}{20}$P Profit per pen = Selling Price per pen − Cost Price per pen = $(\frac{1}{20}) – (\frac{1}{25}) = (\frac{1}{100})$ ⇒ Profit Percentage = $\frac{\text{Profit}}{\text{Cost price}}×100$ = ($\frac{\frac{1}{100}}{\frac{1}{25}})×100$
Question : Rani can do the work alone in 10 days, Priya can do the same work alone in 12 days and Guddu can do the same work alone in 15 days. If they do that work together and they are paid INR 6000, then what is the share of Priya?
Option 1: INR 2500
Option 2: INR 1600
Option 3: INR 1800
Option 4: INR 2000
Correct Answer: INR 2000
Solution : Since the efficiency is inversely proportional to the time taken. The ratio of efficiencies of Rani, Priya, and Guddu $=\frac{1}{10}:\frac{1}{12}:\frac{1}{15} = 6:5:4$ So, the share of Priya = $\frac{5}{15}$ × 6000 = INR 2000 Hence, the correct answer is INR 2000.

Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (2)
