@Kashif.
How we can determine the number of sample tests?

For m50 what will be the ratio?
Kashif said:

The general expression is 1:n:2n by volume where n is the number of sample test conducted.

For this firstly, you can understand the two term:
First term:- Nominal mix.
Second term:- Design mix.
First term:- Nominal mix.
Second term:- Design mix.

M30-Depend on design mix (OR) M-30 = 1:1:1.

@Sneka, your assumption is wrong, for M-15 ,the ratio is 1:1.5:3 by yours way summation all 1+1.5+3 = 5.5.

M-5 1:5:10.
M-7.5 1:4:8.
M-10 1:3:6.
M-15 1:1.5:3.
M-20 1:2:4.
M-25 1:1:2.
All of the above grade are made by design mix method.
M-7.5 1:4:8.
M-10 1:3:6.
M-15 1:1.5:3.
M-20 1:2:4.
M-25 1:1:2.
All of the above grade are made by design mix method.

M10 mix was only used for foundation purpose. Because that having less compressive strength.

M10 mix is never used in column, slabs or beams. It is a layer of cement concrete separating the earth to the main concrete in foundation or you can say it is only used in foundation.
