SECTION A : ANALYTICAL REASONING & DECISION MAKING

 

Directions (Question No. 1 – 21): Each group of questions in this section is based on a set of conditions. In answering some of the questions, it may be useful to draw a rough diagram. Choose the response that most accurately and completely answers each question and blacken the corresponding space on your answer sheet.

 

Question No. 13-17: In a game, “words” (meaningful or meaningless) consist of any combination of at least five letters of the English alphabets. A “sentence” consists of exactly six words and satisfies the following conditions:

 

The six words are written from left to right on a single line in alphabetical order.

The sentence can start with any word, and successive word is formed by applying exactly one of three operations to the preceding word: delete one letter; add a letter; replace a one letter with another. At the most three of the six words can begin with the same letter. Except for the first word, each word is formed by a different operation used for the preceding word.

 

13. Which one of the following could be a sentence in the word game?

      (A) Bzaeak blaeak laeak paeak paea paean

(B) Doteam goleam golean olean omean omman

(C) Crobek croeek roeek soeek sxoeek xoeek

(D) Feted freted reted seted seteg aseteg

(E) Forod forol forols forpls orpls morpls

 

Solution:

Let us go by the options.

(A) The words in the given sentence are not in the alphabetical order.

(B) From the first word to the second two letters are relaced.

(C) The given sentence satisfies all the given conditions and hence a sentence in the word game.                         Choice (C)

 

14. If the first word in a sentence is “illicit” and fourth word is “Iicit”, then the third word can be

      (A) Elicit               (B) Implicit            (C) Explicit                 (D) Enlist              (E) Inlist

 

Solution:

The fourth word “licit” can be obtained by performing either delete or replace operation in the third word.

      Only choice (A) can be the third word.                                                                                                              Choice (A)

 

15. If “clean” is the first word in a sentence and “learn” is another word in the sentence, then which one of the following is a complete and accurate list of the positions “learn” cloud occupy?

      (A) Third

      (B) Second, third, fourth

      (C) Third, fourth

      (D) Third, fourth, fifth

      (E) Third, fourth, fifth, sixth

 

Solution:

As ‘clean’ is the first word in the sentence, so at least two operations i.e., delete and add a letter required to get word “learn”.

\ “Learn” cannot be second word in the sentence, but it can be the third or the fourth or the fifth or the sixth word in the sentence.                                                                                                                                                       Choice (E)

 

16. If the first word in a sentence consists of five letters, then the maximum number of letters that the fifth word in the sentence could contain is

      (A) Seven             (B) Four          (C) Eight                          (D) Five                      (E) Six

 

Solution:

To maximise the number of letter in the fifth word, let us not use delete operations and use replace and add operations alternately. So there will be two add operations and thus the maximum number of letters that the fifth word contains will be seven.                                                                                                                                                            Choice (A)

 

17. The last letter of the English alphabet that the first word of a sentence in the word game can begin with is

      (A) t                     (B) w              (C) x                               (D) d                          (E) z

 

Solution:

The first letter of the first word cannot be Z, because at most three words can begin with the same letter.

\ The first word of a sentence can begin with Y.                                                                                                Choice (D)
