Question : Directions: If + means –, – means ×, × means ÷, ÷ means +, then what will come in place of the question mark (?) in the following equation? 137 ÷ 56 × 7 – 6 + 31 = ?
Option 1: 149
Option 2: 163
Option 3: 145
Option 4: 154
Correct Answer: 154
Solution : Given: + means –, – means ×, × means ÷, ÷ means + 137 ÷ 56 × 7 – 6 + 31 = ?
After interchanging the given mathematical signs, we get – 137 + 56 ÷ 7 × 6 – 31 137 + 8 × 6 – 31 137 + 48 – 31 = 154
So, 154 is the answer to the given equation. Hence, the fourth option is correct.
