Solution to Puzzle #179: Crossing the River

This was a very simple puzzle, and therefore I guess I did not challenge enough minds. I got a correct answer from Mahi Saraf – well done Mahi! I would still encourage parents to show this puzzle to their children, it will be an interesting one for children.

I am taking the liberty of reproducing the answer from Mahi.

A=90kg, B=80kg, C=60kg, D=40kg, Supplies=20kg

Here is the sequence:
  1. D and C go
  2. C comes back
  3. A goes
  4. D comes back
  5. C and D go
  6. C comes back
  7. B and supplies go
  8. D comes back
  9. C and D go
Hope you all enjoyed the puzzle!
