• @Roy : " No two sisters give the same combination " means that no two sister gives same pattern of giving gifts ( e.g. if A gives 4 gifts to B then no other sisters can give four to other one.)
  my patter is
  A=1 gift each 4 sisters
  i.e B C D E
  B=4 gifts to 1 sister
  i.e A A A A
  C=3 gifts to 1 sister and 1 gift to another1 sister
  i.e E E E D
  D=2 gift to 1 sister and 2 gift to another1 sister
  i.e B B C C
  E=2 gifts to 1 sister and 1 gift to other1 sister and 1 to another 1 sister
  i.e D D B C

• Question is wrong: D should get exactly 4 gifts. To get 4, options are to get 1 gift from 1 sis , 2 gift from another and then no other combination left. Hence incorrect question

• Hey sangram!! How come A and C both give 1 gift to D because in question it is given that "No two sisters
  give the same combination" ??? Can u explain this?
• 10 years agoHelpfull: Yes(1) No(0)
• A will give 2 to D,as B has already given 4 to A so it will not give anything to D,C will give 1 to D because she has already given 3 to E and E cant give anything to D because all the combinations are fulfilled and cant be repeated.

  and also how can u find combinations for D
