Which of the following numbers will replace the question mark (?) in the given series?

345, 356, 368, 381, 395, ?

Directions: Study the given information carefully to answer the given question.

M, N, O, P, Q, R and Sare seven people live on seven different floors of a building but not necessarily in the same order. The lower most floor of the building is numbered 1, the one above that is numbered 2 and so on till the topmost floor is numbered 7. Each one of them have different income i.e. 3500, 15000, 7500, 9000,11000, 13500 and 5000. (But not necessarily in the same order.)

M lives on an odd-numbered floor but not on the floor numbered 3. The one who has income of 11000 lives immediately above M. Only two people live between M and the one who has income of 7500.

The one who has income of 15000 lives on one of the odd-numbered floors above P. Only three people live between O and the one who has income of 15000. The one who has income of 7500 livesimmediately above O. R earns 4000 more than Q. The one who has income of 3500 lives immediately above the one who has income of 5000.Only one person lives between N and Q. N lives on one of the floors above Q. Neither O nor M has income of 9000. Q does not has income of 7500.

Four clusters have been given out of which three are alike in some manner and one is different. Select the one that is different.

Option 

Select the set in which the numbers are related in the same way as are the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E. g. 13 – Operations on 13 such as adding / subtracting / multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed)
 (30, 93, 1)
