2(3x - 4) = 2x + 12
6x - 8 = 2x + 12
4x = 20
x = 5
AB = 3(5) - 4 = 11
AC = 2(5) + 12 = 22
BC = 7(5) - 2 = 35 - 2 = 33
AC:BC = 22:33 = 2:3
a) n (No. of peoples) = 50
r (No. of prizes) = 3
p(n,r) = p (50,3)

b) n(No. of players)=14
r (No. of players for Batting)=9

c)n(Total applicants)=30
r(tester positions)=4
