What well Centre in place of the question mark (?) in the following questions?
` 3435+3+ 51 =? xx13`

Options

A. 92
B. 87
C. 96
D. 89

Answer

To solve the equation \( 3435 + 3 + 51 = ? \times 13 \), we will follow these steps:

### Step 1: Simplify the left side of the equation
First, we need to add the numbers on the left side of the equation:

\[ 3435 + 3 + 51 \]

Calculating this step-by-step:

1. Add \( 3435 + 3 \):
\[ 3435 + 3 = 3438 \]

2. Now add \( 3438 + 51 \):
\[ 3438 + 51 = 3489 \]

So, the left side simplifies to \( 3489 \).

### Step 2: Set up the equation
Now we have:

\[ 3489 = ? \times 13 \]

### Step 3: Solve for the question mark (?)
To find the value of \( ? \), we need to divide both sides of the equation by 13:

\[ ? = \frac{3489}{13} \]

### Step 4: Perform the division
Now, we will perform the division:

1. Divide \( 3489 \) by \( 13 \):
- \( 3489 \div 13 = 268.38461538461536 \)
- However, we need to find the integer part of this division.

2. Performing the long division:
- \( 13 \) goes into \( 34 \) two times (2).
- \( 2 \times 13 = 26 \), subtract \( 26 \) from \( 34 \) gives \( 8 \).
- Bring down \( 8 \) to make \( 88 \).
- \( 13 \) goes into \( 88 \) six times (6).
- \( 6 \times 13 = 78 \), subtract \( 78 \) from \( 88 \) gives \( 10 \).
- Bring down \( 9 \) to make \( 109 \).
- \( 13 \) goes into \( 109 \) eight times (8).
- \( 8 \times 13 = 104 \), subtract \( 104 \) from \( 109 \) gives \( 5 \).
- The remainder is \( 5 \).

Thus, the integer part of the division is \( 268 \).

### Step 5: Conclusion
Therefore, the value of \( ? \) is \( 268 \).

### Final Answer
\[ ? = 268 \]
