Assuming ISA standard sea level conditions (288.16 K, density of 1.225 kg/m3, g = 9.81 m/s2, R = 287 J/(kg-K))

Q. Assuming ISA standard sea level conditions (288.16 K, density of 1.225 kg/m³, g = 9.81 m/s², R = 287 J/(kg-K)), the density (in kg/m³) of air at Leh, which is at an altitude of 3500 m above mean sea level is (accurate to two decimal places).

Ans: 0.85 to 0.88
