Ration used in M10 concrete is 1:3:6 1 Cement, 3 Sand & 6 Aggregate
from M30 onwards the mixes are designed. they dont have a const ration as in the case of mixes like M10, M15....,M25
M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.

To calculate the amount of sand and metal (aggregate) in M10 and M20 grades of concrete, you first need to determine the mix ratio. M10 is typically a 1:3:6 ratio (cement:sand:aggregate) and M20 is a 1:1.5:3 ratio. For a given volume of concrete, calculate the total parts in the mix, then divide the total volume by the sum of the parts to find the volume of each component. Finally, multiply the volume of sand and aggregate by their respective mix ratios to find the quantities needed.

The recommended water-to-Quikrete ratio for optimal concrete mixing is about 0.6 gallons of water per 80-pound bag of Quikrete.

the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
