How many $D$'s are there in the following series which are immediately followed by $W$ but not immediately preceded by $K$?
$K, D, C, W, K, D, W, N, K, G, D, W, W, D, H, K, V, D, W, Z, D, W$

$A$ group of letters is given which are numbered $1, 2, 3, 4, 5$ and $6$. Below are given four alternatives containing combinations of these numbers. Select the combination of numbers so that the letters arranged accordingly form a meaningful word.
$E, L, B, M, A, G$
$1, 2, 3, 4, 5, 6$

Each of the following questions is based on the following alphabet series.
$A, B, C, D, E, F, G, H, I, J, K, L, M$
$N, O, P, Q, R, S, T, U, V, W, X, Y, Z$
If the first and the second letters interchange their positions,and similarly the third and the fourth letters,the fifth and the sixth letters,and so on,which letter will be the seventeenth from your right?

If it is possible to make a meaningful word with the second,the fifth,the tenth,and the twelfth letters of the word $METROPOLITAN$,which of the following will be the third letter of that word? If no such word can be made,give $X$ as the answer,and if more than one such word can be made,give $M$ as the answer.

Arrange the given words in alphabetical order and choose the one that comes in the second place:

How many such pairs of letters are there in the word $EXCURSION$,each of which has as many letters between them in the word as they have in the English alphabet?
