On which of the following does the correct proportion of ingredients of concrete depend upon?
lf X,Y and Z are fineness moduli of coarse fine and combined aggregates, the percentage (P) of fine aggregates to combined aggregates is
$$1) P = \frac{Z - X}{Z - Y} \times 100$$
$$2) P = \frac{X - Z}{Z - Y} \times 100$$
$$3) P = \frac{X - Z}{Z + Y} \times 100$$
$$4) P = \frac{X + Z}{Z - Y} \times 100$$
