By interchanging the given two numbers (not digits) which of the following equations will not be correct?
5 and 6
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 5 - 3 × 6 + 4 = -3.
Given conditions: 5 and 6
Option 1: 5 - 3 × 6 + 4 = -3
After interchanging the expression becomes:
= 6 - 3 × 5 + 4 = -3
= 6 - 15 + 4
= 10 - 15
= -5 is not equal to 3
Hence, Option 1 is the correct answer.
