1200-200:40*5*5

Let's solve the expression step by step:

1. First, divide 200 by 40: $$200 : 40 = 5$$
2. Then, multiply the result by 5: $$5 \cdot 5 = 25$$
3. Next, multiply the result by 5 again: $$25 \cdot 5 = 125$$
4. Finally, subtract the result from 1200: $$1200 - 125 = 1075$$

So, the final answer is:

Answer: 1075
