A Happy MMXVIII From Transum

Monday 1st January 2018

This month's puzzle is taken from the excellent book I have been reading during the holiday called "Can You Solve My Problems" by Alex Bellos. I have just read the problem called "The Shrivelled Spuds" which I present to you here:

A pile of potatoes weighing 100kg is put in the sun. Ninety nine per cent of the weight of the potatoes is made up of water. After a day some of the water evaporates., with the result that 98 per cent of the weight of the potatoes is now made up of water. What's the new weight of the potatoes?
