Which two signs should be interchanged to make the equation mathematically correct?
78 + 3 ÷ 26 − 8 × 24 = 25
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. × and +.
Given equation: 78 + 3 ÷ 26 − 8 × 24 = 25
Option 1: × and +
After interchanging the expression becomes:
= 78 × 3 ÷ 26 − 8 + 24 = 25
= 9 − 8 + 24
= 25 = 25
As we have found our answer, there is no need to check further options.
Hence, × and + is the correct answer.
