Question : 173 of 200

Marks: +1, -0

If 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={Z -X }/{Z -Y }×100

(2)

P={ X -Z }/{ Z -Y}×100

(3)

P={ X -Z }/{ Z+Y}×100

(4)

P={ X +Z }/{ Z -Y}×100

Solution:

P = ({X-2}/{2-Y})×100

X = Fineness modulus of coarse aggregrate
Y = FM of fine aggregrate
Z = FM of combined.
