Question 1091286
<br>As the problem is stated, the only way I can make sense out of it is if "turnover" is the total cost of the goats and sheep....<br>
In that case, if x is the number of goats and y is the number of sheep, then we need to find integer solutions to the equation
{{{900x + 1500y = 100000}}}<br>
Unfortunately, there will be no solutions in integers.  On the left, both 900 and 1500 are multiples of 3, so the sum 900x + 1500y will be a multiple of 3.  But the number on the right is not a multiple of 3.<br>
If I have interpreted the problem correctly, there is no solution.<br>
If I have not interpreted the problem correctly, then resubmit the question making it clear what the question is.
