Follow the given instructions. Each item has a question followed by two statements.The average of three quotation for a particular item is 120. Is the highest quotation less than or equal to 139?
I The lowest quotation is 90.
II. One of the quotations is 125.

Options

A. if the question can be answered with the help of Statement I alone
B. if the question can be answered with the help of Statement II alone
C. if the question can be answered with the help of both the statements but not with the help of either statement itself
D. if the question cannot be answered even with the help of both the statements.

Answer

To solve the problem, we need to determine if the highest quotation is less than or equal to 139, given the average of three quotations is 120.

### Step-by-Step Solution:

1. **Calculate the Total Sum of Quotations:**
- The average of the three quotations is given as 120.
- To find the total sum of the quotations, we multiply the average by the number of quotations:
\[ \text{Total Sum} = \text{Average} \times \text{Number of Quotations} = 120 \times 3 = 360 \]

2. **Analyze Statement I:**
- Statement I states that the lowest quotation is 90.
- If the lowest quotation is 90, we can denote the three quotations as \( Q_1, Q_2, Q_3 \) where \( Q_1 = 90 \) (the lowest).
- Let \( Q_2 \) and \( Q_3 \) be the other two quotations. Thus, we have:
\[ Q_1 + Q_2 + Q_3 = 360 \implies 90 + Q_2 + Q_3 = 360 \implies Q_2 + Q_3 = 270 \]

3. **Analyze Statement II:**
- Statement II states that one of the quotations is 125.
- This means either \( Q_2 = 125 \) or \( Q_3 = 125 \). Let's assume \( Q_2 = 125 \).
- Then, substituting \( Q_2 \) into the equation from Statement I:
\[ 90 + 125 + Q_3 = 360 \implies Q_3 = 360 - 215 = 145 \]

4. **Determine the Highest Quotation:**
- Now we have the three quotations: \( Q_1 = 90 \), \( Q_2 = 125 \), and \( Q_3 = 145 \).
- The highest quotation among these is \( 145 \).

5. **Compare with 139:**
- We need to check if the highest quotation (145) is less than or equal to 139.
- Since \( 145 > 139 \), we conclude that the highest quotation is not less than or equal to 139.

### Conclusion:
- Both statements together allow us to conclude that the highest quotation is 145, which is greater than 139. Therefore, the answer to the question is **No**.

### Final Answer:
- The answer is that the highest quotation is **not less than or equal to 139**.
