By interchanging the given two signs and numbers which of the following equation will be correct?
+ and –, 7 and 3
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 3 × 4 ÷ 2 + 7 – 5 = 16.
Given conditions: + and –, 7 and 3
Option 3: 3 × 4 ÷ 2 + 7 – 5 = 16
After interchanging the expression becomes:
7 × 4 ÷ 2 - 3 + 5 = 16
7 × 2 - 3 + 5 = 16
14 - 3 + 5 = 16
16 = 16
