The humid heat is defined as the amount of heat required to raise the temperature of 1kg dry air plus water vapour it contains by 1k. We can find this by the following relation:
Cs = Specific heat of gas + {specific heat of vapour(humidity)}.
Cs = 0.2 + (1.5*0.01) = 0.215.
Cs = Specific heat of gas + {specific heat of vapour(humidity)}.
Cs = 0.2 + (1.5*0.01) = 0.215.

Humid Heat = Sp heat of gas + H * Sp.heat of vapour.
= 0.2+0.01 * 1.5=.215.
= 0.2+0.01 * 1.5=.215.

I think it is inadequate data.
Because H"=Ch*dT we need dry temperature.
