Puzzle for Today
Puzzle No. 442 – Friday 22nd March
My doctor prescribed some red tablets to be taken, one each day, from 1st January this year. They come in packets of ten. Later my doctor decided that I should also take some green tablets, one each day, from 1st February. The green tablets come in packs of seven. I am very conscientious about taking my tablets and I was wondering what would be the first date (if any) when I would be opening new packets of red and green tablets on the same day.
