In an experiment to estimate the volume of air in a soil sample using a measuring cylinder, it was found that:
initial volume of water = p cm³
volume of soil before mixing with water = q cm³
Final volume of water after adding soil = r cm³
From the data above, which of the following deductions is correct?
r = p + q
r > p + q
q = r - p
r < p + q
