A Queen (78kg), the Prince (36kg) and the King (42kg) are stuck at the top of a tower. A pulley is fixed to the top of the tower. Over the pulley is a rope with a basket on each end. One basket has a 30kg stone in it. The baskets are enough for 2 people or 1 person and the stone. For safety's sake there can't be more than a 6kg difference between the weights of the baskets if someone's inside. How do the people all escape?

• Stone will be down initially. Prince enters in the top basket then stone comes up and prince reaches down. Then king enters in to the top basket by keeping the stone out and prince enters in the down basket. Now, king is down and prince is up. Then, only stone basket goes down and empty basket will come up. Now queen goes down and king and stone comes up. Now again stone alone goes down. Now prince goes down and stone again goes up. Again stone alone goes down. Now king goes down and prince comes up. Then stone from down comes up, and prince goes down. :)
