Calculate the pressure at a height of 6500m above the sea level if the atmospheric pressure is 10.145 N/cm2 and temperature is 25℃ assuming air is incompressible. Take density of air as 1.2 kg/m3. Neglect variation of g.

(a) 4.98 N/cm^2

(b) 2.49 N/cm^2

(c) 1.24 N/cm^2

(d) None of the mentioned

I had been asked this question in an interview for job.

This question is from Pressure at a Point in Compressible Fluid in chapter Pressure and Its Measurement of Fluid Mechanics
