In ready mix concrete quantity of material depend on the grade of concrete we can not say any exact quantity without the proportion of concrete

can you tell me the proportion of M25 concrete?

It is depend on the W/C ratio

1. For 0.5 Cum Pan Mixer what will be Compacted Volume ?

2. What all Aggregates Sizes Required with respect to their Size and Quantity?

3. Amount of Water and Cement Max can be used?

4. Amount of Sand ?

Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. (I think it should be 1.7 instead of 1.5)

Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg. ( I think it should be 3.3 instead of 3 )

Some engineers using an emperical method:
If you want 250 kg/cm2
Cement = 250+(50 to 100)
Cement = 250+100 = 350
Cement = 350/50 = 7 bags
W/c = 0.5
Water 175 liters
Use sand 0.4 cum and coarse aggregates 0.8 cum
Remember, use this method for small jobs.
These method components will not give accurate 1 cum.
