If X, Y and Z are the fineness modulli of coarse, fine and combined aggregates, the percentage (P)
of fine aggregates to combined aggregates, is
(A) P = [(Z - X)/(Z - Y)] × 100
(B) P = [(X - Z)/(Z - Y)] × 100
(C) P = [(X - Z)/(Z + Y)] × 100
(D) P = [(Z + X)/(Z - Y)] × 100
of fine aggregates to combined aggregates, is
(A) P = [(Z - X)/(Z - Y)] × 100
(B) P = [(X - Z)/(Z - Y)] × 100
(C) P = [(X - Z)/(Z + Y)] × 100
(D) P = [(Z + X)/(Z - Y)] × 100
