29.
If 20 kg of coarse aggregate is sieved through 80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron and 150 micron standard sieves and the weights retained are 0 kg, 2 kg, 8 kg, 6 kg, 4 kg respectively, the fineness modulus of the aggregate, is
7.30
7.35
7.40

Why do we divide 740 by 100?

Sieve Retained Reained perce Cumaltive size
80 0 0 0

40 2 10 10

20 8 40 50

10 6 30 80

4.75 4 20 100

2.36 0 0 100

1.18 0 0 100

600 0 0 100

300 0 0 100

150 0 0 100
740
Fineness modulus =740/100,
= 7.4.
