Question : Directions: If + means −, − means ×, × means ÷ and ÷ means +, what will come in place of (?) in the following equation? 83 ÷ 12 – 65 × 13 + 47 = ?
Option 1: 92
Option 2: 96
Option 3: 79
Option 4: 108
Correct Answer: 96
Solution : Given: 83 ÷ 12 – 65 × 13 + 47 = ?
On replacing the mathematical signs, we get – = 83 + 12 × 65 ÷ 13 – 47 = 83 + 12 × 5 – 47 = 83 + 60 – 47 = 96
Hence, the second option is correct.
