Оп a new scale of temperature (which is linear) and called the W scale, the freezing and boiling points of water are 3 9 ∘ W and 23 9 ∘ W respectively. What will be the temperature on the new scale, corresponding to a temperature of 3 9 ∘ C on the Celsius scale?NEET 2008 (Screening)

Given, ​ T f ​ = 3 9 ∘ W T b ​ = 23 0 ∘ W ​ We know that, ​ 10 0 ∘ C − o ∘ C T b ​ − T f ​ ​ = 3 9 ∘ C T − 3 9 ∘ C ​ 100 239 − 39 ​ = 39 T − 39 ​ 100 200 ​ = 39 T − 39 ​ T − 39 = 2 × 39 = 7 8 ∘ W T = 39 + 78 = 11 7 ∘ W ​
