Question : Directions: If + means ×, – means ÷, × means +, and ÷ means −, then what will be the value of the following expression? 42 × 168 – 8 ÷ 4 + 3 = ?
Option 1: 62
Option 2: 45
Option 3: 56
Option 4: 51
Correct Answer: 51
Solution : Given: + means ×, – means ÷, × means +, and ÷ means − 42 × 168 – 8 ÷ 4 + 3 = ?
After interchanging the given mathematical signs, we get – ⇒ 42 + 168 ÷ 8 – 4 × 3 ⇒ 42 + 21 – 4 × 3 ⇒ 42 + 21 – 12 ⇒ 51
So, 51 is the answer to the given equation. Hence, the fourth option is correct.
