Formula is (X-Z)/(Z-Y)*100.
Here X - 6.8, Y - 2.6, Z - 5.4.

FM mean?

Fineness Modulus-FM.

NABIN CHANDRA DAS FROM GIMT said:   10 years ago
{(6.8-5.4)/(5.4-2.6)}*100 = 50%

x = 6.8, y = 2.6, z = 5.4.

C is correct answer.

How can we determine the value of X, Y and Z?

Vishvas said:   8 years ago
X = % coarse aggregates.
Y = % fine aggregates.
Z = % combined aggregates.

Pritam said:   8 years ago
When it is given "to be combined", the solution is given as (6.8-5.4)/(6.8-2.6).

Naveen Kallan said:   8 years ago
If it is the ratio of fine to coarse then only ans is 50%.

If it is percentage then ans is X-Z/X-Y = 33.33%.
