If two numbers are in ratio 3:5 and their LCM is 150, find the numbers.

The correct answer is A: 30 and 50. Let numbers be 3k and 5k. Since gcd(3,5)=1, LCM = 3k×5k/1 = 15k. Given LCM = 150, so 15k = 150, k = 10. Numbers are 30 and 50.

A merchant marks goods at ₹500 and offers 20% discount. If cost price is ₹300, find profit percentage.

The correct answer is B: 26.67%. Selling Price = 500 - 20% of 500 = 500 - 100 = ₹400. Profit = 400 - 300 = ₹100. Profit% = (100/300)×100 = 33.33%... Rechecking: 100/300 = 1/3 = 33.33%. Hmm, should be D.

A trader sells two articles for ₹1,200 each. On one he gains 25% and on the other he loses 20%. What is his overall profit or loss percentage?

The correct answer is A: 2.3% loss. Step 1: For article 1 (25% gain): If SP = ₹1,200 and gain = 25%, then CP = 1200/1.25 = ₹960. Step 2: For article 2 (20% loss): If SP = ₹1,200 and loss = 20%, then CP = 1200/0.80 = ₹1,500. Step 3: Total CP = 960 + 1500 = ₹2,460. Step 4: Total SP = 1200 + 1200 = ₹2,400. Step 5: Loss = 2460 - 2400 = ₹6

A book's price increases by 12% one month and decreases by 10% the next month. If the original price was ₹500, what is the final price?

The correct answer is B: ₹504. Step 1: After 12% increase: Price = 500 × (1 + 0.12) = 500 × 1.12 = ₹560. Step 2: After 10% decrease: Price = 560 × (1 - 0.10) = 560 × 0.90 = ₹504. Therefore, option B is correct.
