The new scale is called time.
The reading on new scale is twice the reading on celsius scale when the temperature of a certain body is 373K.
When temperature is 373K(boiling point of water), reading on celsius scale = 100
so reading on time scale = 100×2 = 200
The reading on fahrenheit scale is 17/15th the reading on time scale when the temperature of body is 20⁰C.
reading on fahrenheit scale for 20⁰C = (9×20)/5 + 32 = 36+32 = 68
reading on time scale =68×(15/17) = 60Upper fixed point of a scale is boiling point of water. In time scale, it is 200.
Lower fixed point of a scale is freezing point of water. Let it be L.
we found that, 20⁰C = 60 on time scale. thusSo lower fixed point in time scale is 25.
