If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘−’, what will come in place of the question mark (?) in the following equation?
93 A 3 C 15 B 5 D 12 = ?

The correct answer is Option 3 (94).

To solve the given equation, we replace the letters with their corresponding mathematical operators based on the rules provided in the question:

'A' stands for division (÷)
'B' stands for multiplication (×)
'C' stands for addition (+)
'D' stands for subtraction (−)

The original equation is:

$93 \text{A} 3 \text{C} 15 \text{B} 5 \text{D} 12=?$

Substituting the corresponding mathematical operations into the equation, we get:

$93÷3+15\times 5-12$

Now, follow the BODMAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction) to simplify the equation step-by-step:

Step 1: Perform Division

$93÷3=31$

The equation becomes:

$31+15\times 5-12$

Step 2: Perform Multiplication

$15\times 5=75$

The equation becomes:

$31+75-12$

Step 3: Perform Addition

$31+75=106$

The equation becomes:

$106-12$

Step 4: Perform Subtraction

$106-12=94$

Hence, the value that replaces the question mark (?) is 94.
