What value will come in place of the question mark (?) in each of the following questions ?
`220%of 345-4.5%of 580=?`

Options

A. 732.9
B. 723.9
C. 713.9
D. 731.9

Answer

To solve the equation \( 220\% \text{ of } 345 - 4.5\% \text{ of } 580 = ? \), we will follow these steps:

### Step 1: Calculate \( 220\% \text{ of } 345 \)

To find \( 220\% \text{ of } 345 \), we convert the percentage to a decimal and multiply:

\[ 220\% = \frac{220}{100} = 2.2 \]

Now, multiply by 345:

\[ 2.2 \times 345 = 759 \]

### Step 2: Calculate \( 4.5\% \text{ of } 580 \)

Next, we calculate \( 4.5\% \text{ of } 580 \):

\[ 4.5\% = \frac{4.5}{100} = 0.045 \]

Now, multiply by 580:

\[ 0.045 \times 580 = 26.1 \]

### Step 3: Subtract the two results

Now we will subtract the result from Step 2 from the result of Step 1:

\[ 759 - 26.1 = 732.9 \]

### Final Answer

Thus, the value that will come in place of the question mark (?) is:

\[ \boxed{732.9} \]
