By interchanging the given two signs and numbers which of the following equation will be correct?
+ and ×, 1 and 2
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 8 × 3 – 4 ÷ 2 + 1 = 3.
Given conditions + and ×, 1 and 2
Option 1: 8 × 3 – 4 ÷ 2 + 1 = 3
After interchanging the expression becomes:
8 + 3 – 4 ÷ 1 × 2 = 3
8 + 3 – 4 × 2 = 3
8 + 3 – 8 = 3
11 - 8 = 3
3 = 3
