Question : Directions: If + means ÷, – means +, × means – and ÷ means ×, then what will come in place of (?) in the given equation? 8 ÷ 5 – 5 × 10 + 2 = ?
Option 1: 40
Option 2: 30
Option 3: 35
Option 4: 45
Correct Answer: 40
Solution : Given: + means ÷, – means +, × means – and ÷ means × 8 ÷ 5 – 5 × 10 + 2 = ?
After interchanging the given mathematical signs, we get – ⇒ 8 × 5 + 5 – 10 ÷ 2 ⇒ 8 × 5 + 5 – 5 ⇒ 40 + 5 – 5 = 40
So, 40 is the answer to the given equation. Hence, the first option is correct.
