Solution.
Let the number of horses and elephants be x and y respectively.
Then there are 100 - (x + y) camels.
So we have,
x + 5y + {100 - (x + y)}/4 = 100
or, 4x + 20y + 100 - x - y = 400
or, 3x + 19y = 300
or, y = (300 - 3x)/19
We cannot solve an equation with two variables. That is why we consider some values of x.
We have to put such values of x for which, we will get an integral y.
We find the set of non-zero solutions:
- x y
- 5 15
- 24 12
- 43 9
- 62 6
- 81 3
