    980 coins

  • Dude

    Correct, Anant.

    There are 980 coins in the collection.

    To check this we add:

    1÷2 + 1÷4 + 1÷5 + 49

    this works out as

    490 + 245 + 196 + 49 = 980, as required.

    To work the answer out from the question, we observe that:

    1÷2 + 1÷4 + 1÷5 = 19÷20

    and we know that there were 49 coins left, so 1÷20 of the collection is 49 coins.

    Which means that the entire collection is 20 x 49 = 980 coins.

    You’re today’s winner.
