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

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

• Most Repeated Question In TCS Guys
  
  d)4-ans.
  A,B,C may be
  (1,2,4) & (4,2,1)
  (1,3,9) & (9,3,1)
  (2,4,8) & (8,4,2)
  (4,6,9) & (9,6,4)
  
  find abs(A+B+C) for these 8 GPs
  7,13,15,19
  
  So,we get 4 different values

• a+b+c,a-b+c,a+b-c,-a+b+c,-a-b+c,-a+b-c,a-b-c,-a-b-c these are the 8 possible outcomes
  But absolute value of a+b+c & -a-b-c are same simillarly
  abs(a-b+c)=abs(-a+b-c)
  abs(a+b-c)=abs(-a-b+c)
  abs(-a+b+c)=abs(a-b-c)
  so the possible values are 4

• The possible values of abs(A+B+C) is
  1,2,4=abs(1+2+4)
  1,3,9=abs(1+3+9)
  1,-2,4=abs(1-2+4)
  1,-3,9=abs(1-3+9)
  so option d). Is it correct?

• Answer is a)5
  
  1. a=1 r=2 or a=1 r=-3 value in both cases 7
  2. a=1 r=-2 ans=3
  3. a=1 r=3 ans= 13
  4. a=2 r=2 ans=14
  5. a=2 r=-2 ans=6
  
  total of 5 distinct values

• b)6-ans
  A,B,C may be
  (1,2,4) & (4,2,1)=7
  (1,3,9) & (9,3,1)=13
  (2,4,8) & (8,4,2)=14
  (4,6,9) & (9,6,4)=19
  (1,-2,4) & (4,-2,1)=3
  (1,-3,9) & (9,-3,1)=7(repeated)
  (2,-4,8) & (8,-4,2)=6
  (4,-6,9) & (9,-6,4)=7(repeated)
  
  find abs(A+B+C)
  3,6,7,13,14,19

• what is the correct answer???? Either 4 or 6???
• 8 years agoHelpfull: Yes(0) No(0)
• Let numbers A,B,C be 2,4,8 which are in g.p.
  2+4+8=14
  -2+4+8=10
  2-4+8=6
  2+4-8=-2
  -2-4+8=2
  2-4-8=-10
  -2+4-8=-6
  -2-4-8=-14
  For absolute value of A+B+C,consider only different values not sign.
  we are getting,2,6,10,14.
  Therefore,answer is 4.
