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?
16 B 8 D 51 A 3 C 57 = ?

The correct option is 168.

To solve the given mathematical equation, we first substitute the letters with their corresponding mathematical operators based on the given instructions:

'A' stands for '÷'
'B' stands for '×'
'C' stands for '+'
'D' stands for '–'

Given equation:

16 B 8 D 51 A 3 C 57 = ?

Replacing the letters with operators, we get:

16 × 8 – 51 ÷ 3 + 57 = ?

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

Step 1: Division

First, perform the division operation (51 ÷ 3):

$51÷3=17$

The equation becomes:

16 × 8 – 17 + 57 = ?

Step 2: Multiplication

Next, perform the multiplication operation (16 × 8):

$16\times 8=128$

The equation becomes:

128 – 17 + 57 = ?

Step 3: Addition and Subtraction

Now, perform addition and subtraction from left to right:

$128+57=185$

$185-17=168$

Thus, the value that comes in place of the question mark (?) is 168.
