Which two numbers (not digits) and which two signs should be interchanged to make the following equation valid?
55 × 5 ÷ 1 – 3 + 14 = 0
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 1, 5 and '+', '–'
55 × 5 ÷ 1 – 3 + 14 = 0
After interchanging 1, 5 and '+', '–', we get: 55 × 1 ÷ 5 + 3 - 14 = 0
= (55 × 1 ÷ 5) + 3 - 14
= (11 + 3) - 14
= 14 - 14
= 0
