Issues Involved:
1. Validity of educational qualifications as a basis for classification under Article 16.
2. Validity of specific provisions in Tamil Nadu Water Supply and Drainage Board Service Regulations and Tamil Nadu Agriculture Engineering Service Rules.
3. Validity of the ratio for promotion between degree-holders and diploma-holders in Tamil Nadu Electricity Board Service Regulations.

Detailed Analysis:

1. Validity of Educational Qualifications as a Basis for Classification:
The court examined whether educational qualifications can form a valid basis for classification under Article 16 of the Constitution. It referred to multiple precedents, including the landmark case of State of J&K v. Triloki Nath Khosa, where it was held that educational qualifications can indeed form the basis of a valid classification. The court emphasized that while educational qualifications can be used for classification, it is essential to maintain a balance between excellence and equality. The court also noted that classifications should not be overly restrictive to the point of jeopardizing the chances of promotion for certain groups.

2. Validity of Specific Provisions in Tamil Nadu Water Supply and Drainage Board Service Regulations and Tamil Nadu Agriculture Engineering Service Rules:
The court addressed two specific grievances:
- Proviso to Regulation 19(2)(b): The proviso allows diploma-holders to be eligible for promotion to the post of Executive Engineer only if they exhibit "exceptional merit." The court upheld this proviso, stating that it is favorable to diploma-holders by providing them a pathway to promotion based on merit.
- Rule 2(b) of the Special Rules for Tamil Nadu Agriculture Engineering Service: This rule prescribes a promotion ratio of 3:2 between degree-holders and diploma-holders. The court upheld this classification, noting that higher educational qualifications are relevant for the higher post due to the nature of the duties involved. The court also considered the historical context and found the ratio to be reasonable and not violative of Article 16.

3. Validity of the Ratio for Promotion in Tamil Nadu Electricity Board Service Regulations:
The court examined the challenge against the Tamil Nadu Electricity Board's decision to fix a promotion ratio of 3:1 between degree-holders (Junior Engineers) and diploma-holders (Supervisors). The court upheld this ratio, noting that the classification is based on higher educational qualifications, which are relevant for certain types of work. The court also considered the potential disruption that changing the ratio could cause, given that the decision had been in place since 1974 and affected a large number of employees. The court found no constitutional infirmity in the classification or the prescribed ratio.

Conclusion:
The court dismissed all the writ petitions, appeals, and special leave petitions, upholding the validity of the classifications and ratios based on educational qualifications in the respective service regulations. The court emphasized the importance of maintaining a balance between social justice and the need for higher education, ensuring that classifications do not unduly restrict promotion opportunities while also recognizing the relevance of higher qualifications for certain posts. The parties were left to bear their own costs.
