Nominal concrete grades are from M5 TO M25 maximum. But still we need to have mix for M 25 also.
Here we take std concrete which starts from M 25 TO M 55 (i.e. 7) from IS 456:2000 table 2.

How can we find out the ratio of M30, M35, M40, M50?

How M30, M35 can be treated as nominal mix?. It falls under the category of design mix.

Above M30 Mix design is done because 5 ingredient of concrete will start above M30 i.e. cement, aggregates, water, admixture.
