Not sure if this is the right forum but can someone please posts a step by step solution to the following.....

A Farmer has to buy 100 animals (at least 1 of each) = £1000. The animals prices are:
1 cow is £50
1 sheep is £10
1 rabbit is 50p
E.g. 10 cows = £500
40 sheep = £400
50 rabbits = £25
So he's bought 100 animals but it only totals £925. Can you work out 100 animals for exactly £1000?

This can only be done through trial and error!

You started the first step - We need to make up 75 pounds.

Now suppose we buy 12 cows and 40 sheeps we get 1000 pounds - but not enough animals!!

So continue...
