What will be the sum of ages of Second youngest and Third eldest person in the group?

Study the given information carefully and answer the following questions. Eight persons M, N, O, P, Q, R, S and T are born in a different month u.q. January, February, March, April, May, June, July, August of different years. Then ages are calculated with respect to 2020. Not consider month for age calculation. No two person’s age is same.Note: If it is mentioned that a person’s age is considered as the last two digits of another person’s birth year, then it will be at any sequence. For example, if the age of X is considered as last two digit of birth year of Y which is 1934. Then the age of X might be either 34 or 43. None of the persons were born before 1970 and after 2010. M was born on1988. M’s birth month is neither August nor he born in first half of the year. T’s age is m square number greater that M’s age and both are born on consecutive months. The difference between the age of M and Q is 6 years. O’s age is equal to the last two digit or birth year of Q and his birth month is not April. R's age is m cube number between Q’s age and O’s age. P’s age is half of the age of S’s age whose age is last two digit of T’s birth year. The Average of ages of M and P is two less than that of the age of N who was born just next month on which P born. O was not born in month of August. Person’s whose birth year is odd on the month, which has even number of days .The Person who is youngest neither born in 30days of month nor born in 31days Month.
