Thank you Mr Shiv Shankar. Please do clarify the following in your reply:-
a)Full expanded form of "Ps"? Is it Nm/sec?
b)Is 1 Ps = 1 BHP? If not 1 Ps = how many BHP?

Ps is unit for power equal to BHP.While specifying power RPM is mentioned to indicate power developed at that RPM ie rotation per minute of crankshaft .While testing engine maximum power generated by engine will be considered and RPM at which that power is generated is also noted.More power at lesser RPM indicates efficiency of engine.Torque is the twisting effort available at end of crank shaft which will be transmitted to axle shaft.
