Which two signs should be interchanged to make the equation mathematically correct?
104 ÷ 13 + 60 - 5 × 2 = 115
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ÷ and -.
Given equation: 104 ÷ 13 + 60 - 5 × 2 = 115
Option 1: ÷ and -
After interchanging the expression becomes:
= 104 - 13 + 60 ÷ 5 × 2 = 115
= 104 - 13 + 12 × 2
= 104 - 13 + 24
= 115 = 115
As we have found our answer, there is no need to check further options.
Hence, ÷ and - is the correct answer.
