144 beads were distributed among some children| If there were 3 children fewer each child would have got 16 beads | How many children shared the beads?

Question: 144 beads were distributed among some children. If there were 3 children fewer each child would have got 16 beads . How many children shared the beads?
Solution:

Let the number of children be x.
Therefore if there would be 3 children less then each would have get 16 beads.
That means number of children now=x-3
Therefore the condition can be written as :
144/(x-3)=16
of 16(x-3)=144
or 16x=144+48
or 16x=192
or x=192/16
x=12
Therefore numbers of children =12 ANS.
