Dear Student,

If θ is the reading on new scale and θ0 is its zero fixed point
let n is the number of parts between lower and upper fixed parts, thenT-0100=θ-θ0nwhen, T=0°C, θ=10°C0100=10-θ0nθ0=10°Cwhen, T=50°C, θ=60°C50-0100=60-10n12=50nn=100At celcius scale, boiling point of water=100°C
On new scale, let this be θ,100-0100=θ-10n1=θ-10100100=θ-10θ=100+10=110°C
so, option A is correct
