Question : Directions: If + means –, × means +, – means ÷, and ÷ means ×, what will come in place of the question mark (?)? 89 × 36 – 9 + 2 ÷ 11 = ?
Option 1: 71
Option 2: 79
Option 3: 83
Option 4: 92
Correct Answer: 71
Solution : Given: 89 × 36 – 9 + 2 ÷ 11 = ?
On interchanging the mathematical signs, we get – = 89 + 36 ÷ 9 – 2 × 11 = 89 + 4 – 2 × 11 = 89 + 4 – 22 = 93 – 22 = 71
Hence, the first option is correct.
