Letter Repeating Series
Letter Repeating Series
Letter Repeating Series:
This type of questions usually of a series of small letters which follow a certain pattern. However, some letters are missing from the series. These missing letter are then given in a proper sequence as one of the alternatives. The candidate is required to choose this alternative as the answer.
Example : aab ___aaa____bba____
(a) baa (b) abb (c) bab (d) aab (e) bbb
Solution: We proceed step by step as shown below :
Ex. In the following series, choose the alternative which contains the numerals to be filled in the marked spaces, in the coorect 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
Sol. 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 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 correspnds 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 corresponds to C. Thus, the question mark below C is to be replaced by 3. Thus, DA'CB corresponds to 1, 2, 3, 4.
Hence, the answer is (a).
1. ccbb __ aa __ cc __ bbbaa __ c
(a) acbc (b) babca (c) baba (d) acba
Answer: (b) : The series is ccc bbb aaa/ccc bbb aaa/c. Thus, the pattern ccc bbb aaa is repeated.
2. C B __ __ D __ B A B C C B
__ __ 1 2 4 3 __ __ ? ? ? ?
a __ a b __ c __ b __ __ __ __
(a) 3, 4, 4, 3 (b) 3, 2, 2, 3 (c) 3, 1, 1, 3 (d) 1, 4, 4, 1
Answer: (c) :Comparing the positions of the capital letters, numbers and small letters, we find: a corresponds to C and 1 corresponds to a, So, a and 1 correspond to C.b corresponds to A and 2 corresponds to b. So, b and 2 correspond to A. Also, 4 corresponds to D.
So, the remaining number i.e. 3 corresponds to B. So, BCCB corresponds to 3, 1, 1, 3.
