What will come in place of question mark (?) in the following questions ?
24% of 240 + 12% of 480 = ?

Options

A. `57.60`
B. `116.20`
C. `115.20`
D. `211.520`

Answer

To solve the equation \( 24\% \text{ of } 240 + 12\% \text{ of } 480 = ? \), we will follow these steps:

### Step 1: Calculate 24% of 240
To find 24% of 240, we can convert the percentage to a fraction and multiply:

\[ 24\% = \frac{24}{100} \]

Now, calculate:

\[ 24\% \text{ of } 240 = \frac{24}{100} \times 240 \]

### Step 2: Simplify the calculation
We can simplify the calculation by canceling out the zeros:

\[ = \frac{24 \times 240}{100} = \frac{5760}{100} = 57.6 \]

### Step 3: Calculate 12% of 480
Next, we will calculate 12% of 480 in a similar manner:

\[ 12\% = \frac{12}{100} \]

Now, calculate:

\[ 12\% \text{ of } 480 = \frac{12}{100} \times 480 \]

### Step 4: Simplify the calculation
Again, we can simplify the calculation:

\[ = \frac{12 \times 480}{100} = \frac{5760}{100} = 57.6 \]

### Step 5: Add the two results together
Now we will add the results from Step 2 and Step 4:

\[ 57.6 + 57.6 = 115.2 \]

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

\[ \boxed{115.2} \]
