Question : Directions: If + means –, – means ×, × means ÷, and ÷ means +, then what will come in place of (?) in the given equation? 30 + 5 – 2 × 10 ÷ 2 = ?
Option 1: 50
Option 2: 31
Option 3: 80
Option 4: 60
Correct Answer: 31
Solution : Given: + means –, – means ×, × means ÷, and ÷ means + 30 + 5 – 2 × 10 ÷ 2 = ?
After interchanging the given mathematical signs, we get – ⇒ 30 – 5 × 2 ÷ 10 + 2 ⇒ 30 – 5 × 0.2 + 2 ⇒ 30 – 1 + 2 = 31
So, 31 is the answer to the given equation. Hence, the second option is correct.
