What will come in place of (?) in the following questions ?
`? = {("65% of 3400") div ("45% of 900")} "of 648"`

Options

A. 3022
B. 3536
C. 3468
D. 3290

Answer

To solve the problem step by step, we need to evaluate the expression given in the question:

**Step 1: Calculate 65% of 3400.**

\[ 65\% \text{ of } 3400 = \frac{65}{100} \times 3400 \]

Calculating this gives:

\[ = 0.65 \times 3400 = 2210 \]

**Step 2: Calculate 45% of 900.**

\[ 45\% \text{ of } 900 = \frac{45}{100} \times 900 \]

Calculating this gives:

\[ = 0.45 \times 900 = 405 \]

**Step 3: Divide the results from Step 1 and Step 2.**

Now we need to divide the result from Step 1 by the result from Step 2:

\[ \frac{2210}{405} \]

Calculating this gives:

\[ = 5.46 \text{ (approximately)} \]

**Step 4: Now, we need to multiply this result by 648.**

So we calculate:

\[ 5.46 \times 648 \approx 3536.88 \]

Since we are looking for an integer value, we can round this to:

\[ \approx 3536 \]

Thus, the value that comes in place of (?) is approximately **3536**.
