If ‘P’ means ‘addition’, ‘Q’ means ‘subtraction’, ‘R’ means ‘multiplication’, and ‘S‘ means ‘division’. What will be the value of the following expression?
76 P 42 S 6 Q 22 P (8 R 15)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 181.
Given the equation: 76 P 42 S 6 Q 22 P (8 R 15)
Given conditions: ‘P’ means ‘addition’, ‘Q’ means ‘subtraction’, ‘R’ means ‘multiplication’, and ‘S‘ means ‘division’
After interchanging, the expression becomes:
= 76 + 42 ÷ 6 - 22 + (8 × 15)
= 76 + 42 ÷ 6 - 22 + 120
= 76 + 7 - 22 + 120
= 83 - 22 + 120
= 181
