​If 'P' means '+', 'Q' means '–', 'R' means '×' and 'S' means '÷', then find the value of the following expression.

$$\tfrac{2}{3}$$​ S $$\tfrac{1}{3}$$​ Q 7 P 7 R 5​​​​​​​

Correct option is C

Let's solve the given equation;

$$\tfrac{2}{3}$$​ S $$\tfrac{1}{3}$$​ Q 7 P 7 R 5

$$=\tfrac{2}{3}$$ $$\div$$​ $$\tfrac{1}{3}$$ - 7 +  7 $$\times$$ 5​

=2 - 7 + 7 $$\times$$​5 

=2 - 7 + 35

=37 - 7
