Correct Answer :

Option C

212

Solution :

To find the value that replaces the question mark (?), we first decode the operators in the given equation based on the provided representations:
- 'A' stands for addition (+)
- 'B' stands for subtraction (-)
- 'C' stands for multiplication (×)
- 'D' stands for division (÷)

The given equation is:
6 C 7 C 8 B 71 A 11 B 32 C 2 = ?

Replacing the letters A, B, and C with their corresponding mathematical operators, we get:
6 × 7 × 8 - 71 + 11 - 32 × 2

Now, we apply the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction) to solve the expression step-by-step.

Step 1: Perform the multiplication operations
First, calculate the product of 6, 7, and 8:
6 × 7 × 8 = 42 × 8 = 336
Next, calculate the product of 32 and 2:
32 × 2 = 64

Substituting these values back into the expression, we get:
336 - 71 + 11 - 64

Step 2: Perform the addition and subtraction operations
Let's group the positive and negative numbers together:
(336 + 11) - (71 + 64)
= 347 - 135
= 212

Therefore, the value that will come in place of the question mark is 212.
