Question : Directions: If + means –, – means ×, × means ÷, ÷ means +, then what will come in place of the question mark (?) in the following equation?
14 – 7 ÷ 42 × 6 + 33 = ?
Option 1: 72
Option 2: 84
Option 3: 68
Option 4: 56
Correct Answer: 72
Solution :
Given:
+ means –, – means ×, × means ÷, ÷ means +
14 – 7 ÷ 42 × 6 + 33 = ?
After interchanging the signs the equation becomes –
14 × 7 + 42 ÷ 6 – 33 = ?
14 × 7 + 7 – 33
98 + 7 – 33 = 72
So, the equation equals to 72. Hence, the first option is correct.
