Question : Directions: If + means –, – means ×, × means ÷, ÷ means +, then what will come in place of the question mark (?) in the following equation? 23 – 5 ÷ 240 × 8 + 14 = ?
Option 1: 145
Option 2: 119
Option 3: 131
Option 4: 124
Correct Answer: 131
Solution : Given: + means –, – means ×, × means ÷, ÷ means + 23 – 5 ÷ 240 × 8 + 14 = ?
After interchanging the given mathematical signs, we get – ⇒ 23 × 5 + 240 ÷ 8 – 14 ⇒ 23 × 5 + 30 – 14 ⇒ 115 + 30 – 14 = 131
So, 131 is the answer to the given equation. Hence, the third option is correct.
