Detailed Solution

Let θ0 be the lower fixed point of the faulty thermometer and n be the number of divisions between its lower and the upper fixed points. If a temperature C on Celsius scalecorresponds to temperature q on the scale of faulty thermometer, then   C−0100=θ−θ0n   ……..(i)Here, θ0=5∘;n=95−5=90 and θ=59∘Therefore, the Eq. (i) becomesC−0100=59−595−5C=5490×100C=60∘C
