In the faculty of Reverse-Engineering, 500 second year students study numeric methods, 300 second year students study automatic control of airborne vehicles and 300 second year students study them both. How many students are there in the faculty if the second year students are approximately 50% of the total?	Choose the correct choice from the following options.
A) 1100	B) 1200	C) 1150	D) 1000	E) 1050
Total number of students studying both are 500 + 300 - 300= 
<gadget id="calculator">500 + 300 - 300</gadget>
<output>500</output>
500 (Subtracting the 300 since they were included in the both the other numbers already).   So 50% of total is 500, so 100% is 1000   Answer is 1000
