If + means −, − means ×, × means ÷, and ÷ means +, what will be the value of the following expression?
45 × 9 ÷ 12 – 5 + 3
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 62.
Given equation: 45 × 9 ÷ 12 – 5 + 3
Given conditions:
+ means −, − means ×, × means ÷, and ÷ means +
After interchanging the expression becomes:
= 45 ÷ 9 + 12 × 5 - 3
= 5 + 12 × 5 - 3
= 5 + 60 - 3
= 62
Hence, option 4 is the correct answer.
