An arbitrary scale has the ice point at `-20^(@)` and the steam point at `180^(@)`. When the thermometer reads `5^(@)`, then find the read of centigrade thermometer.

What is the steam point in a thermometer?

What is ice point in a thermometer?

On a hypothetical scale X , the ice point is 40^(@) and the steam point is 120^(@) . For another scale Y the ice point and steam points are -30^(@) and 130^(@) respectively. If X -reads 50^(@) The reading of Y is

On a hypothetical scale X, the ice point is 40^(@) and the steam point is 120^(@) . For another scale Y the ice point and steam points are -30^(@)and130^(@) respectively. If X-reads 50^(@) The reading of Y is

On a hypothetical scale A the ice point is 42^(@) and the steam points is 182^(@) For another scale B . The ice points is -10^(@) and steam point in 90^(@) . If B reads 60^(@) . The reading of A is.
