What steps can be taken by a State government to ensure that the total number of Ministers complies with this clause within six months after the President's appointment of a date?
To ensure that the total number of Ministers complies with this clause within six months after the President's appointment of a date, the State government can take the following steps:

1. Review the current composition of the Council of Ministers to identify any excess ministers beyond the specified limit.
2. Determine the required reduction in the number of Ministers based on the percentage mentioned in the clause or the specific number set by the first proviso, whichever is applicable.
3. Initiate discussions with the affected Ministers and the Chief Minister to determine a fair method for reducing the size of the Council of Ministers. This may involve offering ministerial positions to some members of the ruling party who are not currently in the Council of Ministers or considering other forms of political accommodation.
4. Once an agreement is reached on the reduction, formally announce the changes to the public and the affected Ministers.
5. Administer the oaths of office and secrecy to the newly appointed or retained Ministers according to the forms set out in the Third Schedule.
6. Implement any necessary administrative adjustments to ensure a smooth transition and maintain efficient governance within the State.
