There are 15 identical balloons, 6 identical pencils, and 3 identical erasers.
We need to distribute these items among 3 children, such that each child gets at least 4 balloons and 1 pencil.
Therefore, every person gets 4 balloons and 1 pencil.
After distribution, we have 3 balloons, 3 pencils, and 3 erasers remaining.
By arranging the balloons in all possible combinations.
(3, 0, 0) , (2, 1, 0) , (1, 1, 1)
We can arrange (3, 0, 0) in three ways.
We can arrange (2, 1, 0) in six ways.
We can arrange (1, 1, 1) in only one way.
So, we can arrange balloons among three children in 10 ways.
Likewise, we can also arrange 3 pencils in 10 ways and 3 erasers in 10 ways.
Therefore, the total number of ways is 10 x 10 x 10 = 1000 ways
