What will come in the place of the question mark ‘?’ in the following question?
Correct Answer :
22
Solution :
The correct answer is 22 (which corresponds to Option 3).
To solve this expression, we follow the standard order of operations (BODMAS / PEMDAS rule): Brackets/Parentheses, Orders/Exponents, Division and Multiplication (from left to right), and Addition and Subtraction (from left to right).
The given mathematical expression is:
Step 1: Solve the operations inside the brackets (parentheses).
We first calculate the value inside the brackets:
Now, substitute this back into the expression:
Step 2: Perform multiplication and division from left to right.
First, evaluate the multiplication:
Substitute this value back into the expression:
Next, perform the division:
Substitute this result back into the expression:
Step 3: Perform addition and subtraction from left to right.
First, carry out the addition:
Finally, perform the subtraction:
Thus, the value that replaces the question mark ‘?’ is 22.
