Question : Directions: If + means subtraction, – means multiplication, ÷ means addition and × means division, then what is the value of the following expression?
3 – 21 + 153 × 17 ÷ 26
Option 1: 84
Option 2: 80
Option 3: 76
Option 4: 58
Correct Answer: 80
Solution :
Given:
+ means subtraction, – means multiplication, ÷ means addition, and × means division.
3 – 21 + 153 × 17 ÷ 26
On replacing the signs in the equation, the equation becomes –
= 3 × 21 – 153 ÷ 17 + 26
= 3 × 21 – 9 + 26
= 63 – 9 + 26
= 89 – 9
= 80
So, 80 is the required answer. Hence, the second option is correct.
