(1) Bob and Mia together own a total of 800 shares.- this doesn't give any sufficient information. insufficient.

(2) Bob and Lou together own a total of 500 shares.-this doesn't give any sufficient information. insufficient.

Even after combining S1 & S2 , we cant say how many shares Lou has...
So Answer is E

From statement 1) we know that B + M = 800 However this is insufficient we know nothing about Lou's shares.

From statement 2) we know that B + L = 500 again not enough information.

Combining both and substitute one equation in the other.

Let B = 800 - M >> 800 - M + L = 500 >> L = M - 300 , still insufficient since I have 2 variables in the equation.

E is the answer.
