Question : Directions: If + means ×, × means –, – means ÷ and ÷ means +, then what will come in place of the (?) in the following equation? 250 – 10 + 10 × 5 ÷ 2 = ?
Option 1: 247
Option 2: 167
Option 3: 320
Option 4: 234
Correct Answer: 247
Solution : Given: 250 – 10 + 10 × 5 ÷ 2 = ?
After interchanging the given mathematical signs, we get – ⇒ 250 ÷ 10 × 10 – 5 + 2 ⇒ 25 × 10 – 5 + 2 ⇒ 250 – 5 + 2 ⇒ 247
So, 247 is the answer to the given equation. Hence, the first option is correct.
