Which two signs and two numbers should be interchanged in the equation given below to make the following equation correct?
5+8×2÷4=12
Show answer & explanation
Correct answer: A
Explanation
Given equation:
5 + 8 × 2 ÷ 4 = 12
Testing Option (A): Interchange signs × and +, and numbers 2 and 8:
5 × 2 + 8 ÷ 4
Applying the BODMAS rule:
= 5 × 2 + (8 ÷ 4)
= 10 + 2
= 12
Since LHS = RHS, Option (A) is the correct interchange.
