Solution

## The correct option is D none of theseGiven:In z scale,Boiling point of water = 65ZFreezing point = 14ZSolution:In Fahrenheit scale,Boiling point of water =212 °FFreezing point of water = 32°Fn−32212−32=−98+1465+14⇒n−32180=−8479⇒n−32=−8479×180⇒n−32=−191.39⇒n=32−191.39Therefore, n= -159.39 FHence, D is correct option(None of these).
