Two coils P and S have 2000 turns and 5000 turns respectively. A current of 1A in the coil causes a flux per turn of 0.8 \times 10^{-3} weber to link with P and 0.4 \times 10^{-3} weber through S. The ratio of coefficient of self-inductance of P and the coefficient of mutual inductance of P and S is
