If 'P' denotes 'addition', 'D' denotes 'subtraction', 'S' denotes 'multiplication', and 'V' denotes 'division', then what will be the value of the following expression?
{20 D (25 D 33} V {-5 S 4 D (-6)} P 56 V (-27 P 13)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. - 6.
Given expression: {20 D (25 D 33} V {-5 S 4 D (-6)} P 56 V (-27 P 13)
On replacing the sign:
{20 - (25 - 33} ÷ {-5 × 4 - (-6)} + 56 ÷ (-27 + 13)
{20 + 8} ÷ {-20 + 6} + 56 ÷ (-14)
28 ÷ (-14) - 4
-2 - 4 = -6
