Question $4($Aggregate gradation analysis$)$

The results of sieve analysis of three different sources of aggregates $(A,B$ and C $)$ are shown in Table below. Also shown in the table are the specification requirements for a road project. Propose an aggregate blend for the project using suitable proportions of the three aggregate sources.
