Question

Four pirates, Jack, Dusty, Bart, and Will, want to bury their treasure on an island in the Caribbean. They arrive near the island with their ship but to get to shore they must row on a boat. The four pirates must carry the treasure to shore using the boat, but the boat can only carry 100 kg, otherwise, it will sink. Jack weighs 90kg, Dusty weighs 85kg, Will and Bart are young pirates and weighing 40kg each. The treasure chest weighs 20kg. As pirates are greedy, no pirate can be left alone on the shore or on the ship with the treasure, or else he will steal it. How do the four pirates get to the shore and how do they manage to take the treasure to the shore with them?

Answer 1

Lets say the ends are denoted as S(start) and T(target)

Currently, J(90), D(85), B(40), W(40) are all at Start position with the treasure chest.
First, B & W go to the Target end.
Then, B returns back with the bot. W can be left alone, since treasure is on Start position only.

Then J(90) goes along with boat to the other end..
From other end, W comes back.

So, Now, D(85), B(40), W(40) are on start position with chest, while J(90) is on other end.

Then B(40), W(40) & Chest(20) go to other end..
And B comes back, Leaving W and J on the target side with currency chest.

Now B(40), D(85) is on start side, and W(40), J(90) are on the target side with currency chest.

Then D(85) goes to target side, and W(40) returns back from there.
Now W(40) and B(40) both go from start to target side..
