IBPS PO Reasoning: Blood Relations and Ordering questions with solutions

Q1. Eight persons P, Q, R, S, T, U, V, and W were born in different years 1982, 1986, 1990, 1993, 1996, 1999, 2000, and 2009, but not necessarily in the same order. It is assumed that all of them were born on the same date in different years. All age calculations are done taking the base year as 2021. - Two persons were born between R and Q. - The age of R is a perfect square of 5. - One person was born between Q and W. - Three persons were born between W and V. - P is younger than V and older than R. - The age of P is a multiple of 7. - The sum of V's age and S's age is 56. - The difference between the age of S and the age of T is 18. What is the age of U?

1. 31
2. 35
3. 39
4. 12

Answer: 31

R's age is a perfect square of 5, so R must be 25 years old, meaning birth year 1996. Using the spacing clues and the conditions on P, V, S, and T, the arrangement becomes fixed. The remaining person U corresponds to age 31.
