A soil sample has a liquid limit = 45 percent, plastic limit = 25 percent, and shrinkage limit = 15 percent. For a natural water content of 30 percent, the consistency index will be:

After a certain time lapse, clay A achieved 50% average consolidation and clay B achieved 20% average consolidation. Find the ratio of coefficient of consolidation of clay A to that of clay B. The time factor Tv for U = 50% is 0.2 and for U = 20% is 0.03. Both clays have same drainage path lengths.

During a standard Proctor compaction test, the mass of the wet soil sample is found to be 1800 g and its water content is 13%. If the volume of the Proctor mould used is 1000 cm3, then the dry density of the soil sample is:
