Answer
ladies pay 250$ for room rent
waiter got 20$
ladies get back 30$
or
in your way
ladies paid 90x3 = 270$ (Total expense)
less waiter tip = 20$
so room rent 250$
Rs 10 not gone anywhere it was just an imaginery amount.
Total Cost = Rs. 3 women * Rs 90 each = Rs 270
Waiter's Tip = Rs 20
Hence Room Rent = Rs 270- Rs 20 = Rs 250
$ 270 already includes the dollar kept by clerk. (90*3). Total expenditure 270. Each women has been returned back $ 30. So Total $ 300.
