    Answer



    18



    Assume that initial there were 3*X bullets.

    So they got X bullets each after division.



    All of them shot 4 bullets. So now they have (X - 4) bullets each.

    But it is given that,after they shot 4 bullets each, total number of bullets remaining is equal to the bullets each had after

    division i.e. X



    Therefore, the equation is

    3 * (X - 4) = X

    3 * X - 12 = X

    2 * X = 12

    X = 6


    Therefore the total bullets before division is = 3 * X = 18
