Which two signs should be interchanged to make the equation mathematically correct?
18 + 60 ÷ 15 × 24 - 12 = 84
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. × and +.
Given equation: 18 + 60 ÷ 15 × 24 - 12 = 84
Option 1: × and +
After interchanging the expression becomes:
= 18 × 60 ÷ 15 + 24 - 12 = 84
= 18 × 4 + 24 - 12
= 72 + 24 - 12
= 84 = 84
As we have found our answer, there is no need to check further options.
Hence, × and + is the correct answer.
