What value will come in place of question mark (?) in the questions given below?
13.4 x 14.2 - 7.4 x 7.8 = ?

Options

A. 122.56
B. 132.56
C. 130.26
D. 136.56

Answer

To solve the problem \( 13.4 \times 14.2 - 7.4 \times 7.8 = ? \), we will follow these steps:

### Step 1: Calculate \( 13.4 \times 14.2 \)

First, we multiply the first pair of numbers:

\[ 13.4 \times 14.2 = 190.28 \]

### Step 2: Calculate \( 7.4 \times 7.8 \)

Next, we multiply the second pair of numbers:

\[ 7.4 \times 7.8 = 57.72 \]

### Step 3: Subtract the second product from the first product

Now, we will subtract the result of the second multiplication from the result of the first multiplication:

\[ 190.28 - 57.72 = 132.56 \]

### Conclusion

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

\[ \boxed{132.56} \]
