barometric pressure

Problem
Assuming specific weight of air to be constant at 12 N/m3, what is the approximate height of Mt. Banahaw if a mercury barometer at the base of the mountain reads 654 mm and at the same time another mercury barometer at the top of the mountain reads 480 mm.

A.   1642.3 m C.   3051.4 m
B.   1934.5 m D.   1735.2 m
