Question of the Day (13Jun19)


00 : 00 There was a theft at a jewelry shop and all the gold coins were missing. The shopkeeper told police that he did not know the exact number of gold coins in the shop. He also added that when he paired them up in groups of two, exactly one was left unpaired. Similarly, when he paired them up in groups of 3, 4, 5 and 6, exactly one was left unpaired. But when he paired them up in groups of 7, none was left unpaired. What is the minimum number of coins that could have been there at the shop?
