1 REASONING SERIES A series or sequence consists of several terms. In other words, the units of a sequence are called TERMS. Each term in the series has its own importance as there exists certain relationship between the two consecutive terms. All the terms in the sequence follow a certain pattern throughout, the sequence in most cases. We come across several types of questions based r>n any given series. In order to solve such questions you must recognise the pattern of the given series. The questions based on English alphabet series are somewhat easy as you can remember the position of each alphabet readily. But in the case of mixed series or jumbled series, it is vdry difficult to remember the position of each term. A mixed series comprises letters, numbers and symbols and unlike the English alphabet series the number of terms is not fixed in such series. A mixed series may contain any number of terms viz. 26, 28, 30, 32 or 34. Such questions require sufficient practice as there is no definite SHORT CUTS for these questions. The questions on mixed seriescan be divided into two major heade : I. Series of letters and numbers, and II. Series of letters, numbers and symbols. Questions on mixed series tend to judge how quickly you can identify the relationship amongst the given terms (letters, numbers and symbols). Such questions can be solved quickly by counting the terms very fast. Some Important Tips (i) First of all, count the terms in the given series. (ii) Pin-point the middle term, if any. (iii) Write down the total number of letters, numbers and symbols respectively. (iv) Form the groups of five terms, counting from either end so that you can recognise the position of the required term quickly. Series Consisting of Letters & Numbers Directions (1-3) : Read the following letter-number sequence and answer the questions given below : SHM9BWFQ7NJ4VAETX85GKPZR31L Ex.1. Which letter/number is fourth to the left of 16th letter/number from your left? (1) A (2) G (3) 4 Ex.2. If every alternate letter/number starting from 9 is dropped from the above sequence how many letters and numbers respectively will remain in the above sequence? (1) 12 and 3 (2) 11 and 4. (3) 6 and 9 (4) 5 and 10 (5) None of these 4 Ex.3. If the first'fourteen letter-numbers are written in the reverse order which letter/number will be sixth to the left of twelfth letter/number from your right? (1) 9 (2) B (3) H (4) 5 (5) None of these = = ' TRICK : 16-4 = 12th from left 2. (1) Remaining letters/numbers; SHMBF7JVEX5KZ3L Letters => S, H, M, B, F, J, V, E, X, K, Z, L (12) Numbers => 7, 5, 3, (3) 3. (2) The new arrangement: TRICK : = 18th from right Series Consisting of Letters, Numbers & Symbols In order to make series more complicated, letters and numbers are combined with different symbols. Consider the following examples: Directions (4-9): Study the following letter-numbersymbol sequence carefully and answer the questions given below: BD5FE38$M2IK*PT@U9A71 HJ4Q6 Ex.4. What should come in place of the question mark (?) in the following sequence? 5ES, MIP,?, 1HQ (l)tua (2) TU7 91 (4) T91 (5) None of these Ex.5. Which of the following is exactly in the midway between the eleventh from the left end and the 7th from the right end? (1)P (3)T (4) U (5) None of these Ex.6. Which of the following is the sixth to the right of the twentieth from the right end? (1)5 (2) F (3)P (4) K (5) None of these Ex.7. How many such digits are there in the above sequence which are immediately preceded as well as followed by digits?

Ex.8. How many such consonants are there in the above sequence which are immediately preceded by a symbol and immediately followed by a digit? Ex.9.

(DM (2) 8 (3)$ (4) * (5) None of these (4-9) : (i) There are altogether 27 elements in the above sequence. (ii) There are only 14 letters in the above sequence.

(2) llthfromleftend=>i 7th from right end => 1... Remaining elements between I aifd 1: K * P T [ @ ] U 9 A 7 i Middle Term 6.

2 Ex.8. How many such consonants are there in the above sequence which are immediately preceded by a symbol and immediately followed by a digit? Ex.9. If the first fifteen elements are written in the reverse order then which of the following will be eighth to the left of the thirteenth element from right end? (DM (2) 8 (3)$ (4) * (5) None of these (4-9) : (i) There are altogether 27 elements in the above sequence. (ii) There are only 14 letters in the above sequence. (iii) There are only 9 digits in the above sequence. (iv) There are only 4 symbols in the above sequence. (v) The middle term of the sequence is P. Therefore,? = TU7 5.(2) llthfromleftend=>i 7th from right end => 1... Remaining elements between I aifd 1: K * P T ] U 9 A 7 i Middle Term 6. (3) 6th to the right of 20th from the right end means 20-6 = 14th from the right end. There are altogether 27 elements in the above sequence and the middle term, Le., 14th element from either end is P. Therefore, our required answer is option (3). Directions (10-12): Read the following letter-numbersymbol sequence carefully and answer the questions given below : NRA3AF4@LMZP Q 12RTJ7JKL#$' 9 8 G H 3 Ex.10. If the positions of the first five elements are interchanged with that of the last five elements then which of the following will be the eighth element to the right of eleventh element from right? (D H (2) K (3) N (4) 8 - (5) R Ex.11. How many such elements are there in the above sequence which are immediately preceded by letter/ digit/ symbol but immediately followed by a digit? (1) 3 (2) 4 (3) 2 (4) Cannot be determined (5) None of these Ex. 12. What should come in the place of question-mark (?) in the following series? N AFM,?, 4MQ (1) Z (2) Z (3) FL (4) A@P (5) None of these (10-12): (i) There are altogether 32 elements. (ii) There are 17 letters. (iii) There are 8 digits.. (iv) There are 7 symbols. (v) The middle pair of elements is (5) ISHORT-CUT 8th element to the right of 11th element from right means 11-8 = 3rd element from right. But the five elements from right have been interchanged with the five elements from left. Thus Such combination is $ M 2 Therefore, our required answer is option (2). 9.(1) 8th to the left of 13th element from right end means = 21st from the right end. 21 st element from the right end is equivalent to = 7th element from the left and vice-versa. Thus, 1st 15th, 2nd <-> 14th, 3rd *-> 13th, 4th <-> 12th, 5th <-» 11th, 6th <-> 10th, 7th <-> 9th Therefore, required element would be 9th from the left in the original sequence. 9th from left -» M- Such Combinations are: Thus, there are seven such elements.
