Show Answer

Correct Answer :

Option B

÷ and −

Solution :

The correct option is ÷ and −.

Given equation:
2+10×124÷24=8

Interchanging the signs ÷ and , the equation becomes:
2+10×12÷424=8

Now, solving the Left-Hand Side (LHS) step-by-step using the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction):

Step 1: Perform Division (12÷4)
12÷4=3

Substituting this back into the expression:
2+10×324

Step 2: Perform Multiplication (10×3)
10×3=30

Substituting this back into the expression:
2+3024

Step 3: Perform Addition (2+30)
2+30=32

Step 4: Perform Subtraction (3224)
3224=8

Since LHS=RHS=8, interchanging the signs ÷ and makes the equation correct.
