This is a relatively simple puzzle, more geared for children than for adults. My friend Alok Mittal recently asked this question in his Mathematical Circles class and also reminded me that he was asked this puzzle (probably 30 years back!) by my father, who was very fond of puzzles.
It’s 3 pm on Saturday afternoon. By 3 pm on Sunday i.e. in exactly 24 hours, how many times would the minute and the hour hand overlap?
