Answer»

Correct choice is (a) True

The explanation is: For 1 : 2 : 4 CONCRETE, 1m^3 need Labour constant.

Mixing concrete = 3.00 hour/m^3.

Lifting and carrying concrete = 1.20 hour/m^3.

Compacting concrete = 0.80 hour/m^3.

Levelling SURFACE of concrete = 0.10 hour/m^3.

Total= (3+1.2+0.8+0.1) = 5.
