Question : Directions: If + means −, − means ×, × means ÷, and ÷ means +, what will be the value of the following expression? 24 − 20 × 12 + 18 ÷ 5
Option 1: 17
Option 2: 27
Option 3: 480
Option 4: 53
Correct Answer: 27
Solution : Given: + means −, − means ×, × means ÷, and ÷ means +. 24 − 20 × 12 + 18 ÷ 5
On interchanging the symbols in the above equation, we get – = 24 × 20 ÷ 12 − 18 + 5 = 40 − 18 + 5 = 45 − 18 = 27
So, 27 is the answer to the given equation. Hence, the second option is correct.
