Your date of joining is 01.01.1988, i.e., prior to 1995.
Service Division
Your total service of 31 years will be divided into:
1. Past Service, i.e., between 01.01.1988 and 15.11.1995 - 7 years 11 months (less than 10 years).
2. Pensionable Service, i.e., between 15.11.1995 and 30.05.2019 - 23 years 7 months, i.e., 24 years.
Pension Entitlement
Your salary was equal to or more than Rs. 2500/- per month as of 15.11.1995. So, you are entitled to a Pension for Past Service of Rs. 85 per month.
In your pensionable service of 24 years, you need to add 2 years of weightage service since you worked for more than 20 years. So, your pensionable service is 24 + 2 = 26 years. Your pensionable salary is Rs. 14,231/-.
Monthly Pension Calculation
Your entitlement to monthly pension is calculated as follows:
(Pensionable Salary x Pensionable Service) / 70
= 14,231 x 26 / 70
= 5286
Therefore, your total pension would be:
For past service: Rs. 85
For pensionable service: Rs. 5286

Total: Rs. 5371

The above calculation is based on my current understanding of the law. The inputs are correct, but there may be a discrepancy between my understanding and the EPFO calculation.
I kindly request you to forward this to someone else for review so that I can correct any errors in my calculations.
Thank you.
