If P means÷, Q means×, R means - and S means +, then what...

Given the new symbol notations:

P means '÷'
Q means '×'
R means '−'
S means '+'

We need to evaluate the expression 175 P 25 S 8 Q 2 R 20 using the new notation.

Step 1: Replace the symbols as per the new notation.

P becomes '÷'
Q becomes '×'
R becomes '−'
S becomes '+'

So, the expression 175 P 25 S 8 Q 2 R 20 becomes: 175 ÷ 25 + 8 × 2 − 20

Step 2: Simplify the expression following the order of operations (BODMAS/BIDMAS).

First, perform division and multiplication from left to right:
- 175 ÷ 25 = 7
- 8 × 2 = 16

So, the expression becomes: 7 + 16 − 20

Now, perform addition and subtraction from left to right:
- 7 + 16 = 23
- 23 − 20 = 3

Final answer: The value of the expression is 3.

So, the correct option is B: 3.
