In the faculty of Reverse-Engineering, 300 second year students study numeric methods, 600 second year students study automatic control of airborne vehicles and 200 second year students study them both. How many students are there in the faculty if the second year students are approximately 70% of the total?	Choose the correct choice from the following options
A) 750  B) 800  C) 900  D) 950  E) 1000
Total number of students studying both are 300 + 600 - 200= 
<gadget id="calculator">300 + 600 - 200</gadget>
<output>700</output>
700 (Subtracting the 200 since they were included in the both the other numbers already).   So 70% of total is 700, so 100% is 1000   Answer is 1000
