Which two signs should be interchanged to make the equation mathematically correct?
49 + 16 ÷ 7 - 36 × 16 = 92
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. × and +.
Given equation: 49 + 16 ÷ 7 - 36 × 16 = 92
Option 1: × and +
After interchanging the expression becomes:
= 49 × 16 ÷ 7 - 36 + 16 = 92
= 112 - 36 + 16
= 112 - 36 + 16
= 92 = 92
As we have found our answer, there is no need to check further options.
Hence, × and + is the correct answer.
