Which of the following interchange of signs would make the given equation correct?
13 + 26 × 2 − 5 ÷ 4 = 6
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. × and ÷.
Given equation: 13 + 26 × 2 − 5 ÷ 4 = 6
Option 1: ÷ and +
After interchanging the expression becomes:
= 13 ÷ 26 × 2 − 5 + 4 = 6
= 0 is not equal to 6.
Option 2: × and ÷
After interchanging the expression becomes:
= 13 + 26 ÷ 2 − 5 × 4 = 6
= 13 + 13 − 5 × 4
= 13 + 13 − 20
= 6 is equal to 6.
As we have found our answer, there is no need to check further options.
Hence, option 2 is the correct answer.
