Let Q be the quantity of 80% solution required then (300 - Q) is the quantity of 30% solution as together the two solutions must equal 300.
Then, [80 x Q] + [30 x (300 - Q)] = [40 x 300]
80Q + 9000 - 30Q = 12000
50Q = 3000
Q = 60...........which means (300 - Q) = 240
60ml of 80% acid solution + 240ml of 30% solution produces 300ml of 40% solution.
