What will come in place of (?) in the following questions ?
`(? - 80)/(15 xx 24) "of 432" xx 25 = 4800`

Options

A. 260
B. 230
C. 250
D. 240

Answer

To solve the equation \((? - 80)/(15 \times 24) \text{ of } 432 \times 25 = 4800\), we will follow these steps:

### Step 1: Understand the Equation
The equation can be rewritten as:
\[ \frac{(? - 80)}{(15 \times 24)} \times (432 \times 25) = 4800 \]
This means we need to isolate the term \((? - 80)\).

### Step 2: Calculate \(15 \times 24\)
First, let's calculate \(15 \times 24\):
\[ 15 \times 24 = 360 \]

### Step 3: Calculate \(432 \times 25\)
Next, we calculate \(432 \times 25\):
\[ 432 \times 25 = 10800 \]

### Step 4: Substitute Back into the Equation
Now we can substitute these values back into the equation:
\[ \frac{(? - 80)}{360} \times 10800 = 4800 \]

### Step 5: Simplify the Equation
To simplify, we can multiply both sides by \(360\):
\[ (? - 80) \times 10800 = 4800 \times 360 \]

### Step 6: Calculate \(4800 \times 360\)
Now, calculate \(4800 \times 360\):
\[ 4800 \times 360 = 1728000 \]

### Step 7: Divide by 10800
Now, we divide both sides by \(10800\):
\[ ? - 80 = \frac{1728000}{10800} \]

### Step 8: Calculate \(\frac{1728000}{10800}\)
Calculating this gives:
\[ \frac{1728000}{10800} = 160 \]

### Step 9: Solve for \(?\)
Now we can solve for \(?\):
\[ ? - 80 = 160 \]
Adding \(80\) to both sides gives:
\[ ? = 160 + 80 = 240 \]

### Final Answer
Thus, the value that will come in place of (?) is:
\[ \boxed{240} \]
