Question : Directions: If + means −, − means ×, × means ÷ and ÷ means +, what will come in place of ? in the following equation? 45 − 3 ÷ 144 × 12 + 38 = ?
Option 1: 123
Option 2: 109
Option 3: 91
Option 4: 95
Correct Answer: 109
Solution : Given: + means −, − means ×, × means ÷ and ÷ means + 45 − 3 ÷ 144 × 12 + 38 = ?
After replacing the symbols according to the instructions the equation becomes – = 45 × 3 + 144 ÷ 12 − 38 = 135 + 12 − 38 = 109
So, after solving the equation the answer is 109. Hence, the second option is correct.
