Title: A Weighty Problem Post by MpAdvisor on Feb 20th, 2013, 8:39pm I have ten boxes which I want to pack into crates. Each crate can carry a maximum of 25 kg. But I only have three crates, and the total weight of the boxes is 75kg: 15 kg, 13kg, 11 kg, 10 kg, 9 kg, 8 kg, 4 kg, 2 kg, 2kg, 1 kg How can I pack the boxes into the crates? |

Title: Re: A Weighty Problem Post by pex on Feb 21st, 2013, 2:28am Looks like it can be done in ten different ways... any additional constraints? [hideb]15+10 = 13+11+1 = 9+8+4+2+2 15+10 = 13+9+2+1 = 11+8+4+2 15+10 = 13+8+4 = 11+9+2+2+1 15+10 = 13+8+2+2 = 11+9+4+1 15+9+1 = 13+10+2 = 11+8+4+2 15+9+1 = 13+8+4 = 11+10+2+2 15+9+1 = 13+8+2+2 = 11+10+4 15+8+2 = 13+11+1 = 10+9+4+2 15+8+2 = 13+10+2 = 11+9+4+1 15+8+2 = 13+9+2+1 = 11+10+4[/hideb] |
