Quantitative Aptitude - MCQ Practice Questions

When selling multiple articles at different profit/loss percentages with equal cost prices, we calculate the overall result by comparing total selling price to total cost price.

Step 1: Calculate selling price of first article (20% profit)

Cost price of first article = ₹1000

Selling price with 20% profit:

Step 2: Calculate selling price of second article (20% loss)

Cost price of second article = ₹1000

Selling price with 20% loss:

Step 3: Find total cost price and total selling price

Step 4: Calculate overall profit or loss

Since the total selling price equals the total cost price, there is no profit and no loss.

Answer: No profit, no loss (Option A)

Let numbers be 4k and 5k. HCF = k = 8. So numbers are 32 and 40

Filling rate = $\frac{1}{10}$, Emptying rate = $\frac{1}{15}$. Net rate = $\frac{1}{10}$ - $\frac{1}{15}$ = $\frac{3}{30}$ - $\frac{2}{30}$ = $\frac{1}{30}$. Time = 30 hours

After 30% discount: 1500 × 0.7 = ₹1050. After additional 10%: 1050 × 0.9 = ₹945
