hey dis is a nice thread but why guys have stopped postin in it....anyways its strange to hear dat no one has even mentioned stephen hawking books...brief history of time....theory...

its easy dude.....actually dey paid...24*3 i.e. 72 ...rite?? now this 72 already includes the 2 rs given to the waiter...i.e. 72-2 = 70...which was the net bill as the manager...
