Calculate the temporary and permanent hardness
P of water sample having the following constituents

W per litre.
\( \mathrm{Ca}\left(\mathrm{HCO}_{3}\right)_{2}=162 \mathrm{mg}, \mathrm{MgCl}_{2}=95 \mathrm{mg} \)
\( \mathrm{NaCl}=585 \mathrm{mg}, \mathrm{Mg}\left(\mathrm{HCO}_{3}\right)_{2}=73 \mathrm{mg} \)
\( \mathrm{CaSO}_{4}=136 \mathrm{mg} \)
(1) \( 200 \mathrm{ppm}, 150 \mathrm{ppm} \)
(2) \( 100 \mathrm{ppm}, 150 \mathrm{ppm} \)
(3) \( 150 \mathrm{ppm}, 200 \mathrm{ppm} \)
(4) \( 150 \mathrm{ppm}, 150 \mathrm{ppm} \)
