Change of scale

The range of temperature in the arbitrary scale is 40 to 290 i.e. 250 divisions....

In Celsius Scale , no.of divisions = 100.

So,
100 divisions of °C Scale corresponds to 250 divisions of Arbitrary Scale.
1 division of °C Scale → 2510 divisions of Arbitrary Scale.
62 divisions of °C Scale → 62x2510 divisions of Arbitrary Scale = 155 divisions.

As the minimum temperature is 40 in the Arbitrary Scale,
62°C = (155 + 40) = 195... [Ans]
