Which two signs and which two numbers(not digits) should be interchanged to yield the value ‘zero’ for the following expression?
2 – 55 + 11 × 4 ÷ 18
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. + and ÷; 2 and 18.
Given equation: 2 – 55 + 11 × 4 ÷ 18
After interchanging + and ÷; 2 and 18, the equation becomes: 18 – 55 ÷ 11 × 4 + 2
= 18 – 5 × 4 + 2
= 18 - 20 + 2
= 20 - 20 = 0
