The HCF of 56, 84, and 140 is:

The correct answer is A: 14. 56 = 2³ × 7, 84 = 2² × 3 × 7, 140 = 2² × 5 × 7. Common prime factors: 2 × 7 = 14.

Two items are bought for ₹1,200 each. One is sold at 20% profit and the other at 15% loss. What is the net profit/loss percentage?

The correct answer is A: 2.5% profit. SP₁ = 1200 × 1.20 = ₹1,440. SP₂ = 1200 × 0.85 = ₹1,020. Total SP = ₹2,460. Total CP = ₹2,400. Profit% = (60/2400) × 100 = 2.5%

A boat's speed in still water is 12 km/h and the speed of the current is 3 km/h. How long will it take to travel 45 km upstream?

If 25% of a number is 80, what is 60% of that number?

The correct answer is A: 192. To solve percentage problems, we first find the original number, then calculate the required percentage of it. Step 1: Find the Original Number Since 25% of the number equals 80, we set up an equation where the unknown number is x. $$0.25 \times x = 80$$ $$x = \frac{80}{0.25} = \frac{80}{\frac{1}{4}

A dealer offers successive discounts of 15% and 10% on an item marked at ₹2000. He still makes a profit of 20% on the cost price. What is the cost price of the item?

The correct answer is B: ₹1300. Step 1: After 15% discount: 2000 - (15% of 2000) = 2000 - 300 = ₹1700. Step 2: After 10% discount on ₹1700: 1700 - (10% of 1700) = 1700 - 170 = ₹1530. Step 3: This is the SP. If profit is 20%, then SP = CP × 1.2, so 1530 = CP × 1.2. Step 4: CP = 1530/1.2 = ₹1275 ≈ ₹1300. So option B is correct.
