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?
29 A 37 B 14 C 3 A (84 D 4) A 46 = ?

The correct option is 91.

To determine the value that replaces the question mark (?), substitute each letter in the expression with its corresponding mathematical operation as given in the problem statement:

• A stands for + (Addition)
• B stands for - (Subtraction)
• C stands for × (Multiplication)
• D stands for ÷ (Division)

The given equation is:

$29\text{A}37\text{B}14\text{C}3\text{A}\left(84\text{D}4\right)\text{A}46=?$

Replacing the letter codes with mathematical operators gives:

$29+37-14\times 3+(84÷4)+46=?$

To evaluate the expression, follow the order of operations specified by the BODMAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction):

Step 1: Simplify the expression inside the brackets (Division)

$84÷4=21$

Substituting this result back into the equation:

$29+37-14\times 3+21+46$

Step 2: Perform Multiplication

$14\times 3=42$

Updating the equation:

$29+37-42+21+46$

Step 3: Perform Addition and Subtraction sequentially from left to right

$29+37=66$

$66-42=24$

$24+21=45$

$45+46=91$

Thus, the value coming in place of the question mark (?) is 91.
