    If a thermometer reads freezing point of water as 20°C and boiling point as 150°C, how much thermometer read when the actual temperature is 60°C         [AFMC 2004]

    A)            98°C                                         

    B)            110°C

    C)            40°C                                         

    D)            60°C

    Correct Answer: A

    Solution :

               Temperature on any scale can be converted into other scale by \[\frac{x-LFP}{UFP-LFP}\] = Constant for all scales \[\frac{x-20}{150-20}=\frac{60}{100}\] Þ \[x=98{}^\circ C\]
