Q2. A shopkeeper buys an article for ₹800 and sells it for ₹1000. What is the profit percentage?
Correct Answer: C
Profit = 1000 - 800 = ₹200. Profit% = (200/800) × 100 = 25%.
Q3. Simple Interest on ₹5000 at 8% per annum for 3 years is:
Correct Answer: B
SI = PRT/100 = 5000 × 8 × 3 / 100 = 120000/100 = ₹1200.
Q4. If A can do a work in 12 days and B can do it in 18 days, how many days will they take together?
Correct Answer: B
A's 1 day work = 1/12; B's 1 day work = 1/18. Together = 1/12 + 1/18 = 3/36 + 2/36 = 5/36. Days = 36/5 = 7.2 days.
Q5. A train travels 360 km in 4 hours. What is its speed in km/h?
Correct Answer: C
Speed = Distance/Time = 360/4 = 90 km/h.
Q6. The ratio of two numbers is 3:5. If both are increased by 10, the ratio becomes 5:7. Find the numbers.
Correct Answer: A
Let numbers be 3x and 5x. (3x+10)/(5x+10) = 5/7. 21x+70 = 25x+50. 4x=20. x=5. Numbers = 15 and 25.
Q7. What is the compound interest on ₹10000 at 10% per annum for 2 years?
Correct Answer: C
A = 10000(1+10/100)² = 10000 × 1.21 = ₹12100. CI = 12100-10000 = ₹2100.
Q8. If selling price = ₹750 and loss = 25%, find the cost price.
Correct Answer: C
SP = CP × (100-Loss%)/100. 750 = CP × 75/100. CP = 750×100/75 = ₹1000.
Q9. Two successive discounts of 20% and 10% are equivalent to a single discount of:
Correct Answer: A
Equivalent discount = a+b-ab/100 = 20+10-200/100 = 30-2 = 28%.
Q10. Average of 5 numbers is 27. If one number is excluded, average becomes 25. What is the excluded number?
Correct Answer: A
Sum of 5 numbers = 5×27 = 135. Sum of 4 numbers = 4×25 = 100. Excluded number = 135-100 = 35.
