MHT CET Chemistry question

\lambda_{ClCH_2COONa} = 224\ \mathrm{ohm^{-1}\,cm^2\,gm\,eq^{-1}}, \lambda_{NaCl} = 38.2\ \mathrm{ohm^{-1}\,cm^2\,gm\,eq^{-1}}, \lambda_{HCl} = 203\ \mathrm{ohm^{-1}\,cm^2\,gm\,eq^{-1}}. What is the value of ?

(A)288.5\ \mathrm{ohm^{-1}\,cm^2\,gm\,eq^{-1}}
(B)289.5\ \mathrm{ohm^{-1}\,cm^2\,gm\,eq^{-1}}
(C)388.8\ \mathrm{ohm^{-1}\,cm^2\,gm\,eq^{-1}}Correct
(D)59.5\ \mathrm{ohm^{-1}\,cm^2\,gm\,eq^{-1}}

Answer: (C)

Solution

By Kohlrausch law, ClCH_2COOHClCH_2COONa$}} + λ_{HCl} - λ_{NaCl} =
