Step-by-Step Solution
The wing has treated a single figure as though the demand were spread evenly through the day, and the option shows the spread it hides: a morning at which the route is turning passengers away and an afternoon at which it is carrying air. An additional bus is wanted at one end of that spread whatever the average says, and the average is only comfortable because the empty trips are paying for the full ones. The two seating capacities would alter the arithmetic of the average very slightly and leave its shape untouched. The fare revision bears on what passengers pay. And the length of the route and the running time describe the journey without telling the wing when in the day the crush occurs.
Answer: B) On the six morning trips the buses go out full and leave passengers standing at the roadside, while the eleven trips after two in the afternoon go out less than a quarter filled; the 68 is the two taken together
