Abhi roll a dice and he will get money 3 times the outcome. He gives K to shaylendar for every roll. Finally he gets profit of 3 rupees in every roll. what is the value of k?

a. 3 b.6 c,d (dnt rembr)

• i wrote 3 as ans..
  
  
  as for 1st roll he gets 3 rupees and if he give 3 to shylendar he will have =3
  2 = 6, 6-3=3
  3 = 9, 9-3=6
  4 = 12, 12-3=9................
  so he is getting profit of 3 in every roll....... ans=3

• Probability of dice =1/6
  
  We dont know what abhi is getting when he rolled the dice.
  if he will get all 6,,,,,Then money=18-k here k will be 15 to satisfy the condition.
  but if we'll get all 1,,,,,Then money=3-k here k has to be 0 if we want to satisfy the condition[profit=3]
  similarly it [K] varies with each outcome.
  Therefore, answer is option (D) CANNOT BE DETERMINED because it has many answers.

• when a dice is thrown ,the total outcome will be 6..given ,he gets 3 times the outcome means 6*3=18..
  he gives k for every roll means 6k...
  and gets profit 3 rupees for every roll means 6*3=18 for all roll
  as we know profit =selling price -cost price
  18=6k-18
  36=6k
  k=6...I dont know its correct or wrong..I am not sure
