There is an unbalanced common balance ie., one side is heavier than the other.

If a 1kg weight is placed in left side it is equal to 8 oranges on the otherside.

If we weigh 1 kg on the right side it is equal to 2 oranges on the left side.
Find the weight of each orange

• 200 gms.
  Let y kg be weight of each orange
  Let the left side be x kg heavier than the right side.
  considering first case:
  left side has weight of 1kg
  and right side has 8oranges =8y kg
  or 1+x=8y
  In second case:
  left side has 2oranges and wt.=2y
  right side has wt of 1kg.
  2y+x=1
  Solving these eqns for y we get
  
  y=200 gm.
