By Interchanging the given two numbers which of the following equation will be not correct?
5 and 9
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 9 – 5 × 4 + 6 ÷ 3 = –30.
Given conditions: 5 and 9
Option 2: 9 – 5 × 4 + 6 ÷ 3 = –30
After interchanging the expression becomes:
= 5 – 9 × 4 + 6 ÷ 3 = –30
= 5 – 9 × 4 + 2
= 5 – 36 + 2
= -29 is not equal to -30.
