If 'P' denotes 'addition', 'Q' denotes 'subtraction', 'S' denotes 'multiplication', and 'D' denotes 'division', then what will be the value of the following expression?
5 P (7 S 6) D 3 (8 P 6) S 7 Q 11 (3 S 13 Q 2) P 2 (41 S 9)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 343.
Given equation: 5 P (7 S 6) D 3 (8 P 6) S 7 Q 11 (3 S 13 Q 2) P 2 (41 S 9)
On replacing the letters with sign:
5 + (7 × 6) ÷ 3 (8 + 6) × 7 - 11 (3 × 13 - 2) + 2 (41 × 9)
5 + 42 ÷ 42 × 7 - 407 + 738
5 + 7 - 407 + 738
- 407 + 750 = 343
