#137 Tricky treaty

As my four children sorted their Halloween candy, all was fun and games until James, my youngest, said to another child, 鈥淟ook! I got one more piece than you!鈥�

It was the shot heard around the kitchen table. As they all compared their loot, there was a clamour of children鈥檚 voices:

鈥淚鈥檝e got two more pieces than you!鈥�

鈥淗ey! Why does she have three more than me?鈥�

鈥淎t least I have four more pieces than you!鈥�

鈥淣o fair! You鈥檝e got five more than me!鈥�

鈥淎re you kidding?! You have six more than I do!鈥�

I stopped this by seizing all the sweets and putting them into one big pile. I took three for myself (dad tax) and divided the rest evenly among the kids. Not everyone was happy about this, but that is parenting sometimes. Did James end up with more or less candy than he had at the beginning, and by how much?

Solution

The seven colours are red, orange, yellow, green, blue, indigo and violet. Of these, only red, green and indigo can be made from letters that occur in the names of the other colours. Of these three, red and green can be made from letters in the other two, so indigo must be Lise鈥檚 favourite.
