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

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 - 10 years agoHelpfull: Yes(28) No(5)
- 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? - 10 years agoHelpfull: Yes(3) No(1)
- ans is 6.
- 10 years agoHelpfull: Yes(2) No(3)
- 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

- 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 - 10 years agoHelpfull: Yes(0) No(1)
- what is the correct answer???? Either 4 or 6???
- 9 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.
