The participants in a race consisted of 3 teams with 3 runners on each team. A team was awarded 6 тАУ n points if one of its runners finished in nth place, where 1 ≤ n ≤ 5. If all the runners finished the race and if there were no ties, was each team awarded at least one point?

1. No team was awarded more than a total of 6 points.
2. No pair of teammates finished in consecutive places among the top five places.

Could anyone try to solve the above DS problem?

A is sufficient.
Since there are more than 2*6=12 points to be distributed (there are actually 5+4+3+2+1=15 points to be distributed), then each team got at least 1 point

In B, points could be:
team 1: 5+3+1=9
team 2: 4+2+0=6
team 3: 0+0+0=0
Therefore, not all team got at least 1 point
or it could also be:
team 1: 5+1+0=6
team 2: 4+2+0=6
team 3: 3+0+0=3
Therefore, at least 1 team got 1 point
B is inconclusive
