A basketball team plays 10 games, and it scores 12 points on average. Has this team scored at least 40 points in one game?

1) The team scored 55 points in the first 5 games.
2) The score of each game is at least 9 points.


The sum here is 12*10=120
St1------Not sufficient as 55 points can be divided in various ways for 5 games (40,10,2,2,1) or(10,10,10,10,15)
St2------Sufficient
If score of each game is at least 9 points, then a 40 point in 1 game is not possible since the remaining 80 points (i.e 120-40)
will not help in getting a score of 9 points a game as per statement 2

Ans is B
hit Kudos if u like :)

Ans is B

total 10 games , total average =12 , total score =120
has team scored atleast 40 in 1 game
1) 5 games 55 score
remaining 5 is 65
let in 1 game 39 and remaining 4 games score =65-39
let in 1 game 41 and remaining 4 games score =65-41

or simply 5 games = 55 points
1st game 41 points remaining 4 games = 14
1st game 39 points remaining 4 games = 16

AD out

2) Each game at least 9 score

x + 9x9 = 120
x=120-81
x=39 DEFINITELY NO

B is the answer

The most important thing of all for any Data Sufficiency question is to process statement 1 and statement 2 separately first and only if this doesn't yield an answer we should proceed with statement 1 and 2 combined.
