Directions: Read the following information carefully and answer the question given below. Eight persons P, Q, R, S, T, U, V, and W were born in different years, viz. 1945, 1956, 1961, 1973, 1978, 1989, 1996, and 2007, but not necessarily in the same order. S was born in an odd-numbered year. The difference between the present ages of S and V is 5. Only 3 people were born between V and T. The present age of W is twice the present age of Q. As many people were born between T and Q as between T and P. R was born in one of the years before P. (Calculate all ages with respect to the year 2018.) What is the difference between the ages of S and R?
- 17
- 18
- 19
- 16
Correct answer: 19
Solution
This is a year-based arrangement puzzle. Converting years to ages in 2018 and applying the constraints uniquely fixes the positions/ages of the persons. From the valid arrangement, the difference between the ages of S and R comes out to be 19 years.
