Arbitrary Method of proportioning of concrete:.

The general expression for the proportions of cement, sand and coarse aggregate is 1 : n : 2n by volume. So, option C and D both are wrong.

The option F is correct None of these.

1:1:2 - M25.
1:2:4 - M15.
1:3:6 - M10.

1:2:8 - Wrong proportion, it should be 1:4:8 for M7.5.
1:4:10 - Wrong Proportion, it should be 1:5:10 for M5.
