This type of questions usually consists of a series, of small letters which follow a certain pattern. However, some letters are missing from the series. These missing letters are then given in a proper sequence as one of the alternatives. It required to choose this alternative as the answer.

1)

In the following series,

choose the alternative which contains the numerals to be filled in the marked spaces, in the correct order :

B _ _ D _ _C A B D A C B

_ _ 4 1 3 2 _ _ _  ? ? ? ?

a _ a _ b c _ c _ _ _ _ _ 


A) 1, 2, 3, 4

B) 2, 3, 1, 4

C) 1, 2, 4, 3

D) 2, 1, 4, 3

Answer:

Option A

Explanation:

Clearly, in the second series, 1 occurs at the same position as D occurs in the first series.

So, 1 corresponds to D, Thus, the first question mark below D is to be replaced by 1.

Now, in the third series, c at the eighth place corresponds to A in the first series,

while c at the sixth place corresponds to 2 in the second series. So, 2 corresponds to A.

Thus, the second question mark below A is to be,replaced by 2.

In the third series, a at the first place corresponds to B in the first series.

And a at the third place corresponds to 4 in the second series. So, 4 corresponds to B.

Thus, the question mark below B is to be replaced by 4.

Now, only 3 remains. So, 3 correspbnds to C. Thus, the question mark below C is to be replaced by 3.

Thus, DACB corresponds to 1,2,3,4. Hence, the answer is (a).
