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 ( W_1 W_2 ) with perfect intercooling is given by

Answer: Option B

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 $$\left(\frac{{\text{W}}_1}{{\text{W}}_2}\right)$$  with perfect intercooling is given by $$\frac{{\text{W}}_1}{{\text{W}}_2}=\frac{{\text{n}}_1\left({\text{n}}_2-1\right)}{{\text{n}}_2\left({\text{n}}_1-1\right)}$$
