Question

Solve this:
On a new scale of temperature (which is linear) and called the W
scale, the freezing and boiled points of water are 39oW
and 239oW respectively What will be the temperature on
the new scale, corresponding to a temperature of 39oC on
a Celsius scale ?
(1) 200oW (2) 139oW (3)78o (4)
117oW

Dear Student ,
Let x be the temperature in the new scale corresponding to the
temperature of 390 in C scale
Here in this case we can write that ,
