Which two signs should be interchanged to make the given equation correct?
5 – 24 + 17 × 16 ÷ 4 = 133
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. × and –.
Given equation: 5 – 24 + 17 × 16 ÷ 4 = 133
Option 1: + and ÷
After interchanging the expression becomes:
= 5 – 24 ÷ 17 × 16 + 4 = 133
= -13.58 is not equal to 133.
Option 2: × and –
After interchanging the expression becomes:
= 5 × 24 + 17 - 16 ÷ 4 = 133
= 133 is equal to 133.
As we have found our answer, so, there is no need of checking other options.
Hence, option 2 is the correct answer.
