Seven individuals were born in different years: 1953, 1963, 1968, 1976, 1990, 1993, and 1998. The base year to calculate their ages is 2019.

- No more than two persons were born before P.
- Exactly one person was born between V and S, and neither V nor S has an even-numbered age.
- The number of persons born before U is equal to the number of persons born after Q.
- The age difference between T and S is at least 20 years.
- T was born after R but before Q.
- Either P or U has an odd-numbered age.

Based on these conditions, in which year was T born?

Question

Seven individuals were born in different years: 1953, 1963, 1968, 1976, 1990, 1993, and 1998. The base year to calculate their ages is 2019.

- No more than two persons were born before P.
- Exactly one person was born between V and S, and neither V nor S has an even-numbered age.
- The number of persons born before U is equal to the number of persons born after Q.
- The age difference between T and S is at least 20 years.
- T was born after R but before Q.
- Either P or U has an odd-numbered age.

Based on these conditions, in which year was T born?

Accepted Answer

**Solution:**

1. List the birth years: 1953, 1963, 1968, 1976, 1990, 1993, 1998.

2. Since 2019 is the base year, calculate ages for each year:
   - 1953 → 66 years
   - 1963 → 56 years
   - 1968 → 51 years
   - 1976 → 43 years
   - 1990 → 29 years
   - 1993 → 26 years
   - 1998 → 21 years

3. Condition: No more than two persons born before P, so P's position is either 3rd or earlier.

4. One person is born between V and S, and neither V nor S has an even age. Ages with odd numbers are 51 (1968), 43 (1976), 29 (1990), 21 (1998).

5. The number of persons born before U equals the number born after Q, so U and Q are symmetrically placed.

6. The difference between T and S's ages is at least 20 years.

7. T was born after R but before Q.

8. Either P or U has an odd age.

By analyzing all these constraints, none of the given years (1953, 1968, 1990, 1998) fit T's birth year logically.

Therefore, the answer is **None of these**.

**Answer:** None of these
