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?
905 B 2 C 47 D 903 A 3 = ?

The correct answer is 1556.

To solve the given equation, we first need to substitute the letters with their corresponding mathematical operations as defined:
- A stands for division (÷)
- B stands for multiplication (×)
- C stands for addition (+)
- D stands for subtraction (−)

The given equation is:
$905B2C47D903A3=?$

Substituting the operations, we get:
$905\times 2+47-903÷3$

Now, we solve the expression using the BODMAS rule (Bracket, Of, Division, Multiplication, Addition, Subtraction):

Step 1: Division
First, perform the division operation:
$903÷3=301$

The equation now becomes:
$905\times 2+47-301$

Step 2: Multiplication
Next, perform the multiplication operation:
$905\times 2=1810$

The equation now becomes:
$1810+47-301$

Step 3: Addition
Next, perform the addition operation:
$1810+47=1857$

The equation now becomes:
$1857-301$

Step 4: Subtraction
Finally, perform the subtraction operation:
$1857-301=1556$

Therefore, the value in place of the question mark (?) is 1556.
