Correct Answer :

Option B

54

Solution :

To solve the given equation, we need to substitute the letters with their respective mathematical operators and then simplify the expression using the standard order of operations (BODMAS/PEMDAS rule).

Let us first look at the given mappings for the letters:
- 'A' stands for division (÷)
- 'B' stands for multiplication (×)
- 'C' stands for addition (+)
- 'D' stands for subtraction (-)

The given equation is:
8 B 9 C 49 A 7 D 25 = ?

Substituting the operators in place of the letters, we get the following numerical expression:
8 × 9 + 49 ÷ 7 - 25

According to the BODMAS rule, we must perform division first, followed by multiplication, addition, and finally subtraction.

Step 1: Perform the division operation (49 ÷ 7):
49÷7=7
The expression now becomes:
8 × 9 + 7 - 25

Step 2: Perform the multiplication operation (8 × 9):
8×9=72
The expression now becomes:
72 + 7 - 25

Step 3: Perform the addition operation (72 + 7):
72+7=79
The expression now becomes:
79 - 25

Step 4: Perform the final subtraction operation (79 - 25):
79-25=54

Therefore, the value that will come in place of the question mark is 54.

The correct option is 54.
