Three baseball teams, A, B, and C, play in a seasonal league. The ratio of the number of players on the three teams is 2:5:3, respectively. Is the average number of runs scored per player across all three teams collectively greater than 22?

(1) The average number of runs scored per player for each of the three teams, A, B, and C, is 30, 17, and 25, respectively.

(2) The total number of runs scored across all three teams collectively is at least 220.

number of players = 2x,5x,3x total = 10x

is number of runs / total number of players > 22

from one

total number of runs = 60x , 85x, 75x

average = 220x/10x = 22 suff

from two

assume that total number of runs = 220 / 10x = 22/x , x is positive intiger
it depends on x .........not suff

I say A

My Pick is A
1. we know ratio for number of players in each team and we know average runs scored per team we can total runs scored by each team and then divide by the number of players

But the minimum value x will have will always be >= 1 ,so ofcourse the avg will be less than 22 .
No ??

The total number of runs is AT LEAST 220 which means it could very well be 300 too. If x = 1 and total number of runs is 220, the avg is 22. Is x > 1 and total number of runs is 220, avg is less than 22. If x = 1 and total number of runs is 300, avg is greater than 22.
Hence statement 2 is insufficient.

The ratio of the number of players on the three teams is 2:5:3, respectively. Is the average number of runs scored per player across all three teams collectively greater than 22? Since the ratio of the number of players on the three teams is 2:5:3, respectively, then the # of players on the three teams would be 2x, 5x, and 3x, respectively (for some positive integer multiple x). The average number of runs scored per player equals to total \frac{# \ of \ runs}{# \ of \ players}=\frac{# \ of \ runs}{10x}. So, we are asked to find whether \frac{# \ of \ runs}{10x}>22, or whether # \ of \ runs>220x (1) The average number of runs scored per player for each of the three teams, A, B, and C, is 30, 17, and 25, respectively. The total # of runs for each team would be: 30*2x=60x, 17*5x=85x and 25*3x=75x, so the total # of runs for all teams would be 60x+85x+75=220x. Sufficient. (2) The total number of runs scored across all three teams collectively is at least 220. If the total # of runs is 220 and x=1, then the answer will be NO but if the total # of runs is 230 and x=1, then the answer will be YES. Not sufficient.

Hi Can we use weighted average for statement 1. Ratio of players is 2:5:3 Weighted average/player = (2/10)*30 + (5/10)*17 + (3/10)*25 = 6 + 8.5 + 7.5 = 22 Hence sufficient. Is my logic right? Please let me know. Thanks.
