What will come in place of (?) question mark.
50% of 128 + `(sqrt(16))/(2) xx 4 = ? + 10`

Options

A. 64
B. 62
C. 60
D. 56

Answer

To solve the equation step by step, we start with the given expression:

\[ 50\% \text{ of } 128 + \frac{\sqrt{16}}{2} \times 4 = ? + 10 \]

### Step 1: Calculate 50% of 128
50% of a number is calculated by multiplying the number by 50/100.

\[ 50\% \text{ of } 128 = \frac{50}{100} \times 128 = \frac{1}{2} \times 128 = 64 \]

### Step 2: Calculate \(\sqrt{16}\)
The square root of 16 is:

\[ \sqrt{16} = 4 \]

### Step 3: Substitute \(\sqrt{16}\) into the expression
Now we substitute \(\sqrt{16}\) back into the equation:

\[ 64 + \frac{4}{2} \times 4 = ? + 10 \]

### Step 4: Calculate \(\frac{4}{2}\)
Now we calculate \(\frac{4}{2}\):

\[ \frac{4}{2} = 2 \]

### Step 5: Multiply by 4
Next, we multiply the result by 4:

\[ 2 \times 4 = 8 \]

### Step 6: Substitute back into the equation
Now we substitute this back into the equation:

\[ 64 + 8 = ? + 10 \]

### Step 7: Add 64 and 8
Now we add 64 and 8:

\[ 64 + 8 = 72 \]

### Step 8: Set up the equation
Now we have:

\[ 72 = ? + 10 \]

### Step 9: Solve for ?
To find the value of ?, we subtract 10 from both sides:

\[ ? = 72 - 10 = 62 \]

### Final Answer
Thus, the value that comes in place of the question mark (?) is:

\[ \boxed{62} \]
