It depends on the required grade of concrete, you need to know the particular grade.
The three grades specify the ratios of Cement : Stone : Sand.
M15 = M150 = 1 : 2 : 4
M20 = M200 = 1 : 1.5 : 3
M25 = M250 = 1 : 1 : 2
As you can see there is always two parts sand to one part stone. Higher grades have more cement. So the ratio of stone to the whole is 2:7, 3:11, and 1:4. The percentages are 28.6%, 27.3%, and 25.0%.

How much sand and gravel do you need to make 1 cubic meter of concrete?
To make 1 cubic meter of concrete, you typically need about 1.5 cubic meters of sand and gravel combined. The general ratio for mixing concrete is 1 part cement, 2 parts sand, and 3 parts gravel. Therefore, for 1 cubic meter of concrete, you would need 0.5 cubic meters of cement, 0.75 cubic meters of sand, and 0.75 cubic meters of gravel.
