The second, fourth, fifth and sixth letters are coded as two letters forward while the third letter is coded as three letters forward as in English alphabet. The last letter remains unchanged.

Question 11

If αδγηε is coded as 'ARGUE' and σφλπε is SOLVE, What is παγηελω is?

Accepted Answer

Coding of letters is based on the structure of the word. Logic of coding is very simple. Observe the word and the codes. It gives us following information: If the word consists of four letters, (i) and consonants occupy places at extreme ends only, then those consonants are replaced by [5] while vowels are replaced by either [20] (if both the vowels are same) or [15] (if both the vowels are different). (ii) and the vowels occupy the second and the fourth places only then those vowels are replaced by [25], while the consonants are replaced by [5]. (iii) and the vowels occupy the first and third places only then those vowels are replaced by [30], while the consonants are replaced by [5]. If the word consists of three letters, (i) and the vowels occupy places at extreme ends only then those vowels are replaced by [0], while the consonant is replaced by [5]. (ii) and the consonants occupy places at extreme ends only then those consonants are replaced by [5], while the vowel is replaced by [10]. Thus, in each and every case consonants are coded as [5] but numeric value assigned to vowels varies according to the position of vowels in a particular word.

Question 12

If D becomes H, E becomes J and G becomes N, what will K become in English alphabet?

Accepted Answer

According to given question, D(4) → H(8) E(5) → J(10) On the basis of above relationship , we get the value of K Therefore, K(11) → V(22)

Question 13

If the first and second letters in the word ' COMMUNICATIONS' were interchanged, also the 3rd and the 4th letters, the 5th and 6th letters and so on, which letter would be the 10th letter counting from your right?

Accepted Answer

we can write the given word COMMUNICATIONS as - C → 1 O → 2 M → 3 M → 4 U → 5 N → 6 I → 7 C → 8 A → 9 T → 10 I → 11 O → 12 N → 13 S → 14 After rearrangement , The letter N will be the tenth letter counting from right .

Question 14

A group of alphabets are given with each being assigned a number. These have to be unscrambled into a meaningful word and correct order of letters may be indicated from the given responses. E → (i) R → (ii) D → (iii) I → (iv) S → (v) P → (vi)

Accepted Answer

The pattern is given in the question as below. E → (i) R → (ii) D → (iii) I → (iv) S → (v) P → (vi) Try to form a word by arranging the letters for all given option one by one. Arranging to given word in question ,we get the meaningful word - S → (v) P → (vi) I → (iv) D → (iii) E → (i) R → (ii) Hence , the required answer will be SPIDER.
