Question : Directions: If × means −, ÷ means +, − means ÷, and + means ×, then what will be the value of the following expression? 125 − 25 ÷ 4 + 25 × 4 + 10 = ?
Option 1: 68
Option 2: 62
Option 3: 70
Option 4: 65
Correct Answer: 65
Solution : Given: 125 − 25 ÷ 4 + 25 × 4 + 10 = ?
On interchanging the mathematical signs, we get – = 125 ÷ 25 + 4 × 25 − 4 × 10 = 5 + 4 × 25 − 4 × 10 = 5 + 100 − 40 = 65
Hence, the fourth option is correct.
