Question : Directions: If + means −, − means ×, × means ÷, and ÷ means +, what will be the value of the following expression? 64 × 8 ÷ 24 – 5 + 3 = ?
Option 1: 7
Option 2: 125
Option 3: 64
Option 4: 157
Correct Answer: 125
Solution : Given: 64 × 8 ÷ 24 – 5 + 3 = ?
On interchanging the mathematical sign, we get – = 64 ÷ 8 + 24 × 5 – 3 = 8 + 24 × 5 – 3 = 8 + 120 – 3 = 125
So, 125 is the required answer. Hence, the second option is correct.
