Ten people form a circle. Each one thinks of a number and whisper it to the two neighbours adjacent to her in the
circle. Then each person computes and announces the average of the numbers she had heard from her two neighbours."The number announced by the persons were 44, 12, 23, 27, 40, 46, 56, 61, 69, 36. What was the mumber picked by person who announced the average as 56?"
a) 45 b) 42 c) 28 d) 56

• ans 56
  let a b c d e f g h i j are in circle
  now a+c=2*12=24
  c+e=54
  e+g=92
  g+i=122
  i+a=72
  from the options if u take g=56
  only then these equations will be satisfied

• answer is 56 coz by tryng out each of the answers with the given numbers on ly 56+56=112/2 satisfies the average resulting in 56.

• e+g=92 -1
  g+i=122 -2
  i+a=72 -3
  a+c=24 -4
  c+e=54 -5
  
  [(1)+(2)-(3)+(4)-(5)]/2 ->g=56;
