Following are the statements from all four of them:

Adriana: "Mary is his girlfriend."

Jenny: "Angel is lying."

Angel: "Adriana is lying."

Mary: "Jenny is not his sister."

Can you find out the Dhamaka Singh`s girlfriend and sister among these 4 girls ?

  • Adriana
  • Mary
  • Angel
  • Jenny
    • Explanation :  Suppose if Adriana is his sister and we know that his statement is false.
      
      This will mean that Mary is not his girlfriend.
      
      If Angel is telling the truth, then Adriana must be lying that we have already assumed.
      
      If Jenny is his girlfriend, then she must have spoken a lie as well.
      
      This will mean Angel is speaking the truth which is true in what we have assumed.
      
      At last, Mary said that Jenny is not his sister which is also true as we have made the assumption already that Jenny is his girlfriend.
      
      In what we have assumed, all the statements fit perfectly and the given conditions are satisfied. If you make any other assumption, you will find that one or more conditions are not fulfilled.
      
      Adriana is the sister and Jenny is the girlfriend.
