In n₁ and n₂ are the indices of compression for the first and second stage of compression, then the ratio of work-done on the first and second stages (W₁/W₂) with perfect intercooling is given by

• A. ₁/W₂ = n₂(n₁ - 1)/n₁(n₂ - 1)
• B. ₁/W₂ = n₁(n₂ - 1)/n₂(n₁ - 1)
• C. ₁/W₂ = n₁/n₂
• D. ₁/W₂ = n₂/n₁
