A vessel's light displacement is 12,000 tons. Its heavy displacement is 28,000 tons. When fully loaded it carries 200 tons of fuel and 100 tons of water and stores. What is the cargo carrying capacity in tons?

Correct Answer: Option B — 15,700 tons

Cargo capacity equals heavy displacement minus light displacement, minus deadweight items. Deadweight capacity is 28,000 minus 12,000 equals 16,000 tons. Subtracting 200 tons of fuel and 100 tons of water and stores leaves 15,700 tons for cargo.
