Results of a sieve analysis for Soils A, B, and C are given below. To obtain a more representative sample for further geotechnical testing, a ternary blend was created by uniformly mixing 8000 kg of each soil.

a. If a sieve analysis is conducted on the mixture using the same set of sieves as shown in the table, compute the mass retained (as a percentage) and cumulative percent passing in each sieve.
b. What would be the uniformity coefficient (C_u) and the coefficient of gradation (C_c) of the mixture?
