What should come in place of the question mark (?) in the following questions:
64% of 750 `-:` 4 = ?`-:`5

Options

A. 24
B. 48
C. 300
D. 600

Answer

To solve the equation \( \frac{64\% \text{ of } 750}{4} = \frac{?}{5} \), we will follow these steps:

### Step 1: Calculate 64% of 750
First, we need to find 64% of 750. This can be calculated as:
\[ 64\% \text{ of } 750 = \frac{64}{100} \times 750 \]

### Step 2: Simplify the calculation
Now, simplifying \( \frac{64}{100} \times 750 \):
\[ \frac{64 \times 750}{100} \]
We can simplify \( \frac{750}{100} = 7.5 \), so:
\[ 64 \times 7.5 = 480 \]

### Step 3: Divide by 4
Next, we divide the result by 4:
\[ \frac{480}{4} = 120 \]

### Step 4: Set up the equation
Now, we have:
\[ 120 = \frac{?}{5} \]

### Step 5: Solve for ?
To find the value of ?, we multiply both sides by 5:
\[ ? = 120 \times 5 \]
Calculating this gives:
\[ ? = 600 \]

### Final Answer
Thus, the value that should come in place of the question mark (?) is **600**.
