It was a Sunday, and we nine friends (including myself) went to the sports stadium to watch a football match. After the match, we went to a nearby cafeteria for coffee and some snacks. I went rather unwillingly because I was almost broke; I had only 30 rupees in my pocket. Even before placing the order, we had agreed that each of us would pay an equal share of the bill.
I made it clear that I had only 30 rupees and couldn't pay more. Harish always seemed to have lots of money. "Don't worry," he assured, "A cup of coffee and some snacks wouldn't cost more than 30 rupees each."
Thus assured, I really enjoyed the coffee and the snacks. The waiter brought the bill. The amount was not a nice round figure; an equal share would have meant digging for loose coins into our pockets. As usual Harish showered his generosity on us. "The eight of you pay up 30 rupees each. I will chip in with my 30 rupees, and also pay up the excess amount," he told us.
We were only too glad to comply. The eight of us handed over our respective share of 30 rupees each to Harish, and he put in 20 rupees more than the average share of all the nine us, and paid the bill. What was the bill amount?
