A tanker loads at a terminal within the tropical zone. She will enter the summer zone six days after departing the loading port. She will burn off 45 tons/day and daily water consumption is 8 tons. How many tons may she load over that allowed by her summer load line?

Correct Answer: Option D — 318

Determine total consumable weight burned before entering the summer zone under load line regulations. Multiplying 6 days by the combined daily consumption rate of 53 tons (45 tons fuel plus 8 tons water) yields 318 tons, representing the exact weight allowance permissible over summer marks.
