B. b. 175
C. c. 150
D. d. 85

Answer

To solve the equation \((1700 + 4100 + 5200) / ? = 55\), we will follow these steps:

### Step 1: Add the numbers in the numerator
First, we need to calculate the sum of \(1700\), \(4100\), and \(5200\).

\[ 1700 + 4100 + 5200 = 11000 \]

### Step 2: Set up the equation
Now we can rewrite the equation with the sum we just calculated:

\[ \frac{11000}{?} = 55 \]

### Step 3: Cross-multiply
To eliminate the fraction, we can cross-multiply:

\[ 11000 = 55 \times ? \]

### Step 4: Solve for the unknown
Now, we need to isolate the unknown (denoted by "?"). We can do this by dividing both sides by \(55\):

\[ ? = \frac{11000}{55} \]

### Step 5: Perform the division
Now we will perform the division:

\[ ? = 200 \]

### Conclusion
Thus, the value of the quotient mark is:

\[ ? = 200 \]
