There are two women.one sells 3 marbles for 1 rupee and another 2 marbles for 1 rupee.Both had 30 marbles each left with them.they both combined their marbles and asked a friend to sell them 5 marbles for 2 rupees.if they had sold them separately, they could have got 25 rupees.But they got only 24 rupees from his friend(no commission deducted).
where is that 1 rupee gone?

• The reason is they set a wrong average price, if they have to set the correct price they have to set a different price.
  
  As first woman sells 3 marbles for one rupee, she sells 6 marbles for 2 rupees
  As second woman sells 2 marbles for one rupee, she sells 6 marbles for 3 rupees
  
  They are giving 12 marbles for 5 rupees, they should set this as the price to get the amount of 25 rupees
