three distinct single digit numbers A,B,C are in gp . if abs(X) for real x is the absolute value of x(x if x is positive or zero and -x if x is negative) then different possible values of abs(A+B-C)is

a)5
b)6
c)4
d)3

• Ans -5 a=1,b=3,c=9

• A,B,C may be:
  (1,2,4)&(4,2,1)
  (1,3,9)&(9,3,1)
  (2,4,8)&(4,2,8)
  (4,6,9)&(9,6,4)
  now find abs(A+B-C) for these 8 GPs:
  1,5,5,11,2,10,1,11
  so we get 5 different values:i.e (1,2,5,10,11)
