Each week Manhattan GMAT posts a 700 level GMAT question on our blog and follows up with the answer the next day. Are you up for the challenge?
The velocity, density, and pressure of a certain fluid are related by the equation 5v2 + P = c, where v is the velocity in meters per second, P is the pressure in pascals, and c is a constant. If the velocity of this fluid decreases from 10 meters per second to 5 meters per second, by how many pascals does the pressure in the fluid rise?
(A) 125
(B) 250
(C) 375
(D) 500
(E) 625
