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 +ve or 0 and -x if x is -ve), then the number of different possible values of abs(A+B+C) is Select the correct option
A) 5 B) 6 C) 3 D) 4 E) 7
A,B,C may be   (1,2,4) &amp; (4,2,1)   (1,3,9) &amp; (9,3,1)   (2,4,8) &amp; (8,4,2)   (4,6,9) &amp; (9,6,4)   find abs(A+B+C) for these 8 GPs   7,13,15,19   So,we get 4 different values   ANSWER:4
