45 O 9 O 3 O 25 O 55 O 15
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ÷, ×, +, =, -.
Given equation: 45 O 9 O 3 O 25 O 55 O 15
Option 1: ÷, ×, +, =, -
After interchanging the expression becomes:
= 45 ÷ 9 × 3 + 25 = 55 - 15
= 5 × 3 + 25 = 55 - 15
= 15 + 25 = 55 - 15
= 40 = 40
As we have found our answer, there is no need to check further options.
Hence, ÷, ×, +, =, - is the correct answer.
