Number of ways = 7P3 = 210
.........................................
second method....
Number of ways to select a president = 7
number of ways to select a vice president = 6 ( except the president)
number of ways to select treasurer = 5 (except president and v.president)
so, no. of ways = 7*6*5 = 210
