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
