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:
- D and C go
- C comes back
- A goes
- D comes back
- C and D go
- C comes back
- B and supplies go
- D comes back
- C and D go
Hope you all enjoyed the puzzle!
