Question 5

There is only one runway which will be used by seven flights one by one. P and Q will use the runway neither first nor last. S will use it second after R. M will use it second before O. N will use it after O and before R. Q will use it just before S. Who will use the runway third after O?

Solution

S will use it second after R and Q will use it just before S, => Order will be 'RQS'

N will use it after O and before R, => Order will be 'ONRQS'

Also, M will use it second before O, => M will use it first and then the remaining slot, i.e. second will be taken by P.

Thus, Q will use the runway third after O.

=> Ans - (D)
