Let x be the number of children.

Then the number of oranges given away is 5x, because each child gets 5 oranges and all the oranges are given away.

And the number of pears is 8x+21, because each child gets 8 pears and then there are still 21 left.

The number of pears is 3 times the number of oranges:

8x%2B21+=+3%285x%29
8x%2B21+=+15x
21+=+7x
x+=+3

ANSWERS:
The number of children is x=3.
The number of oranges is 5x = 15.
