Amit is a big fan of cricket. His friend Subham challenges him to guess the total score at some points in an inning of an ODI match. If his guesses will be correct he will get a chance to watch the world cup final in MCG. Now, Amit being a big fan of cricket don't want to miss this opportunity. So, he first analyses some previous matches and comes to following fact: on an average, in a 50-over inning, a team plays 120 balls for singles, 30 for doubles, 30 for fours, 10 for triples, 10 for sixes, 10 for loss of wicket and leaves remaining 90. Now, he tells you this fact and asks you to tell the expected score. Being a very good programmer, your task is to maximize Amit's chances to win this challenge.
