10 mm of water (density = 1000 kg/m^3) and 5 mm of a liquid has the same pressure drop, what is the density of liquid?
A. 500 kg/m^3
B. 1000 kg/m^3
C. 1500 kg/m^3
D. 2000 kg/m^3
The correct option is D. 2000 kg/m^3

Pressure of water = pressure of liquid, => d1h1 = d2h2, => 10*1000 = 5*d2, => d = 2000 kg/m^3.
