Question

On a new scale of temperature (which is linear) and called the `W` scale. The freezing and boiling points of water are `39^(@)W` and `239^(@)W` respectively. What will be the temperature on the new scale, corresponding to a temperature of `39^(@)C` on the Celsius scale?
A. `200^(@)W`
B. `139^(@)W`
C. `78^(@)W`
D. `117^(@)W`

Answer 1

Correct Answer - D
`(C)/(100)=(W-39)/(239-39)`
`(39)/(100)=(W-39)/(200)`
`W=117`
