The following number line shows the temperature in degree Celsius \[{{(}^{o}}C)\] at different places on a particular day. Find P, Q and R. (i) The temperature difference between the hottest and the coldest places is P. (ii) The temperature difference between Yamuna Nagar and Pathankot is Q . (iii) The temperature difference between Pathankot and Kashmir is R.

• A. P Q R \[{{31}^{o}}C\] \[{{8}^{o}}C\] \[{{5}^{o}}C\]                
• B. P Q R \[{{30}^{o}}C\] \[{{18}^{o}}C\] \[{{6}^{o}}C\]                
• C. P Q R \[{{31}^{o}}C\] \[{{18}^{o}}C\] \[{{6}^{o}}C\]                
• D. P Q R \[{{30}^{o}}C\] \[{{7}^{o}}C\]   \[{{8}^{o}}C\]
