By Interchanging the given two numbers which of the following equation will be not correct?
3 and 8
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 6 ÷ 2 × 8 + 3 – 1 = 17.
Given conditions: 3 and 8 are to be interchanged
Option 2: 6 ÷ 2 × 8 + 3 – 1 = 17
After interchanging the expression becomes:
= 6 ÷ 2 × 3 + 8 – 1 = 17
= 16 is not equal to 17.
