Uncertain number of persons in a row. L=2nd from left. W=3rd from right. V=3rd to left of U. #right of U = #left of M. 4 between M and U. N=immediate neighbor of V but not immediate to M. #between W and U = #right of W + 1. How many persons between L and M?
- One
- Three
- Two
- Four
Correct answer: Four
Solution
W=3rd from right=pos(n-2). Right of W=2. Between W,U=2+1=3 → U=pos(n-6). V=U-3=pos(n-9). Right of U=6=#left of M → M=pos7. 4 between M and U: |7-(n-6)|=5 → n=18. L=2, M=7. Between L(2) and M(7): positions 3,4,5,6 = 4 persons.
