ALPHA-NUMERIC SEQUENCE PUZZLE
In such type of questions, a sequence of numbers, letters and symbols is given and a student i5 asked how many times a number/letter/symbol follows a certain rule or which number/letter symbol follows a certain rule.
1. How many symbols are there in the given arrangement each of which is not immediately preceded by a digit but immediately followed by a letter?
4 2 @ + A P 5 > - 6 < T M 4 L Z = 1 - 8 3 D * #
(a) None (b) One
(d) Two (d) Three
The group having given properties is @ + A.
So, the correct option is (B).
NUMBER, RANKING AND TIME SEQUENCE TEST
In these type of problems, a sequence of numbers is given and a student is asked questions same as in the way as asked in Alpha-Numeric Sequence Puzzle.
In ranking test based problems, usually the ranks of one or two persons from the top and from the bottom are mentioned. A student is required to compute either total number of persons or rank of a person.
2. In a class of 60, the girls are twice that of boys, Karim ranked seventeenth from the top. If there are 9 girls ahead of Karim, how many boys are there after him?
(a) 3 (b) 10
(d) 12 (d) 15
Let number of boys = x, then x + 2x = 60
x = 20
There are 16-9=7 boys ahead of Karim. '
Number of boys after Karim =20-1 -7=12
Time Sequence Test:
To solve the time based problems the following information are very useful.
3. If 1st October is Sunday, then 1st November will be _________.
(a) Monday (b) Tuesday
(d) Wednesday (d) Thursday
1st, 8th, 15th, 22nd, and 29th October are Sundays.
So, 31st October is Tuesday.
1st November will be Wednesday.
LOGICAL SEQUENCE OF WORDS
In such type of problems, some words are given. These words have some relationship amongst one another or have a specific sequence.
A student is required to identify this relationship or sequence and put them in a logical sequence.
This sequence may be according to size, age, need, etc.
4. Arrange the words given below in a meaningful sequence.
(a) 3, 4, 5, 1, 2 (b) 4, 3, 1, 5, 2
(d) 4, 1, 3, 5, 2 (d) 4, 3, 1, 2, 5
The order of growing a tree is:
Root, Stem, Leaf, Flower, Fruit.
So the correct option is (B).
The English alphabet contains 26 letters in all.
These starts from A and ends with Z as written below:
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
A rule to find positions of letters is "EJOTY".
Position of letters
A dictionary consists of those letters or words first which commence with A, then B and, so on.
For example, the sequence of letters P, A, M, L and Z in the dictionary is A, L, M, P, Z
For another example, the sequence of words Mango, Apple, Orange, Tomato and Liquid in a dictionary is: Apple, Liquid, Mango, Orange, Tomato.
5. Which of the following words will come in second place, if all of them are arranged alphabetically as in a dictionary?
(a) Crude (b) Crumb
(d) Cruise (d) Crupper
We will consider the fourth letter because first three letters are the same.
The fourth letters are : d, m, i and p. Their order as in dictionary is d, i, m, p.
Therefore, the word in 2nd place is 'Cruise'.
So the correct option is (c).
