Question : Directions: If ÷ means −, − means ×, × means +, + means ÷, what will come in place of the question mark (?)? 132 + 6 – 9 × 13 ÷ 31 = ?
Option 1: 180
Option 2: 206
Option 3: 216
Option 4: 208
Correct Answer: 180
Solution : Given: 132 + 6 – 9 × 13 ÷ 31 = ?
On interchanging the mathematical signs, we get – = 132 ÷ 6 × 9 +13 − 31 = 22 × 9 +13 − 31 = 198 + 13 − 31 = 211 – 31 = 180
Hence, the first option is correct.
