Question 40

Five girls, D, L, N, O and Q, are sitting in a row facing towards the south (not necessarily in the same order). L is second to the right of O. Q is to the immediate right of D. Two girls are between Q and N. How many girls are sitting to the right of D?

Solution

Q is to the immediate right of D.

Q(↓) D(↓)

Two girls are between Q and N.

Here N is possible in two places which are given below in Case(i) and Case(ii).

Case(i) Q(↓) D(↓) _ N(↓)

Case(ii) N(↓) _ _ Q(↓) D(↓)

L is second to the right of O.

In Case(ii), the above-given condition is not possible. So this case is eliminated.

Q(↓) D(↓) L(↓) N(↓) O(↓)

Only 1 girl is sitting to the right of D
