Which one the following costs least?

Question

Accepted Answer

To determine which option costs the least, we need to calculate the total cost for each option and compare them. Let's analyze each option:

1. **75 packets of ₹750 each**:  
   - Total cost = 75 packets × ₹750/packet = ₹56,250

2. **750 packets of ₹7.50 each**:  
   - Total cost = 750 packets × ₹7.50/packet = ₹5,625

3. **7.5 dozen items of ₹750 each item**:  
   - 7.5 dozen = 7.5 × 12 = 90 items  
   - Total cost = 90 items × ₹750/item = ₹67,500

4. **75 dozen items of ₹7.50 each item**:  
   - 75 dozen = 75 × 12 = 900 items  
   - Total cost = 900 items × ₹7.50/item = ₹6,750

Now, let's compare the total costs:
- Option 1: ₹56,250
- Option 2: ₹5,625
- Option 3: ₹67,500
- Option 4: ₹6,750

From the calculations, it is clear that Option 2, with a total cost of ₹5,625, is the least expensive option.

**Explanation for why each of the other options is incorrect:**

- **Option 1**: The total cost is ₹56,250, which is significantly higher than the cost in Option 2.
- **Option 3**: The total cost is ₹67,500, which is the highest among all options, making it incorrect.
- **Option 4**: The total cost is ₹6,750, which is more than the cost in Option 2, thus making it incorrect.

Therefore, based on the calculations, Option 2 is correctly identified as the least expensive option.
