If ‘E’ stands for ‘÷’, ‘U’ stands for ‘×’, ‘A’ stands for ‘+’ and ‘C’ stands for ‘–’, what will come in place of the question mark (?) in the following equation?
16 A 24 C 30 E 15 U 9 = ?

The correct answer is Option 2 (22).

To solve the given mathematical expression, we first need to substitute the specified letters with their corresponding arithmetic operators:

• 'E' stands for '÷'
• 'U' stands for '×'
• 'A' stands for '+'
• 'C' stands for '–'

The original equation given in the question is:

16 A 24 C 30 E 15 U 9 = ?

Replacing the letters with their respective mathematical symbols, we get:

16 + 24 – 30 ÷ 15 × 9 = ?

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

Step 1: Perform Division

First, evaluate the division part (30 ÷ 15):

$30÷15=2$

Substituting this back into the equation:

16 + 24 – 2 × 9 = ?

Step 2: Perform Multiplication

Next, evaluate the multiplication part (2 × 9):

$2\times 9=18$

Substituting this back into the equation:

16 + 24 – 18 = ?

Step 3: Perform Addition

Next, perform the addition (16 + 24):

$16+24=40$

Substituting this back into the equation:

40 – 18 = ?

Step 4: Perform Subtraction

Finally, subtract 18 from 40:

$40-18=22$

Thus, the value that replaces the question mark (?) is 22.
