The total target production of AC machines in February, April and May was what percentage less than the total actual production of Ac Machines over all the five months.

Options

A. 0.462
B. 0.468
C. 0.471
D. 0.476

Answer

To solve the question, we need to find the percentage by which the total target production of AC machines in February, April, and May is less than the total actual production over all five months.

### Step-by-Step Solution:

1. **Identify the Target Production for February, April, and May**:
- From the video transcript, we have:
- February's target = 30
- April's target = 90
- May's target = 100
- **Total Target Production** = February's target + April's target + May's target
- Total Target Production = 30 + 90 + 100 = **220**.

2. **Identify the Actual Production for All Five Months**:
- From the video transcript, the actual production for each month is:
- Month 1 = 70
- Month 2 = 50
- Month 3 = 100
- Month 4 = 80
- Month 5 = 120
- **Total Actual Production** = Month 1 + Month 2 + Month 3 + Month 4 + Month 5
- Total Actual Production = 70 + 50 + 100 + 80 + 120 = **420**.

3. **Calculate the Difference Between Actual Production and Target Production**:
- Difference = Total Actual Production - Total Target Production
- Difference = 420 - 220 = **200**.

4. **Calculate the Percentage Less**:
- To find the percentage less, we use the formula:
\[ \text{Percentage Less} = \left(\frac{\text{Difference}}{\text{Total Actual Production}}\right) \times 100 \]
- Substituting the values:
\[ \text{Percentage Less} = \left(\frac{200}{420}\right) \times 100 \]
- Simplifying this:
\[ \text{Percentage Less} = \left(\frac{200}{420}\right) \times 100 = \left(\frac{10}{21}\right) \times 100 \approx 47.62\% \]

5. **Conclusion**:
- The total target production of AC machines in February, April, and May was approximately **47.62%** less than the total actual production over all five months.
