Question
Which statement will be sufficient to find the person,
who sits second to the right of Q, if L, M, N, O, P and Q are sitting in a straight row facing north but not necessarily in the same order? (I) Three persons sit between L and Q, who sits at the extreme left end of the row. L sit second to the right of P. (II) M sits third to the right of Q, who sits second to the right of L. Three persons sit between L and P.Solution
From statement I alone, we get: Q _____ PÂ _____ L ______ Â So, P sits 2 nd to the right of Q. From statement II alone, we get: L _____ Q _____ PÂ M So, P sits second to the right of Q. Â Either Statement I alone or Statement II alone is sufficient.
