how much do you charge for booking two sleeper train tickets from shanghai to beijing

Hi, there are few trains between the two places with sleepers now. I know T110 has sleeper: it costs CNYCNY497.5/US$82 for soft sleeper and CNY325.5/US$54 for hard sleeper. Besides, the high-speed trains between only takes about 5 h or a little longer.
As for the train schedule and cost, you can find at the website:
