Accepted Answer

Question 6

If NOR is coded as 2-3-6, then how should REST be coded in the same code language?

Accepted Answer

Difference between alphabetical positions of N and O = 1 = difference between 2 and 3 Difference between alphabetical positions of O and R = 3 = Diff. between 3 and 6. Similarly, for REST, difference between R and E = 13, difference between E and S = 14 and difference between S and T = 1 Try All option one by one and we will found that here, Only option (c) follows above condition.

Code for Consonant is it's place value, and code for vowels are given below A ⇒ 1, E ⇒ 2, I ⇒ 3, O ⇒ 4, U ⇒ 5 Therefor M ⇒ 13, A ⇒ 1, N ⇒ 14, G ⇒ 7, O ⇒ 4 So the code for MANGO is 1311474

Question 9

In a certain code, 'MOUSE' is written as 'PRUQC'. How is 'SHIFT written in that same code?

Accepted Answer

From Question M + 3 = P O +3 = R U + 0 = U S -2 = Q E -2 = C In the same way Same way, S +3 = V H + 3 = K I + 0 = I F - 2 =D T -2 = R

Question 10

In a certain code, 'CALANDER' is written as 'CLANAEDR'. How is 'CIRCULAR' written in that code?

Accepted Answer

For question it is clear that, the second and third letters, fourth and fifth letters, sixth and seventh letters of the word mutually interchange positions to form the code. So C ⇒ C I ⇘ R R ⇗ I C ⇘ U U ⇗ C L ⇘ A A ⇗ L R ⇒ R so the code for CIRCULAR is CRIUCALR

Question 11

If FLATTER is coded as 7238859 and MOTHER is coded as 468159, then how is MAMMOTH coded? APPROPRIATE

Accepted Answer

F L A T T E R 7 2 3 8 8 5 9 and M O T H E R 4 6 8 1 5 9 therefore, M A M M O T H 4 3 4 4 6 8 1

Question 12

In a certain code language, GRAPE is written as 27354 and FOUR is written as 1687 . How is GROUP written is that code?

Accepted Answer

GRAPE = 2 7 3 5 4 FOUR = 1 6 8 7 So, G = 2, R = 7, A = 3, P = 5, E = 4, F = 1, O = 6, U = 8, R = 7 GROUP = 2 7 6 8 5

Question 13

If 1 + 4 = 9, 2 + 8 = 18, 3 + 6 = 15 then 7 + 8 =?

Accepted Answer

The given logic is as follows, Sum of the digits + second digit = Answer. i.e., 1 +4 = 5 + 4 = 9 2 + 8 = 10 + 8 = 18 Similarly, 7 + 8 = 15 + 8 = 23.

Accepted Answer

FAT = 6 + 1 + 20 = 27

Question 16

If 0, 1, 2, 3,......, 9 is written as a, b, c, d,.....j, then find dc x f - (bf - d) x d.

Accepted Answer

dc x f - (bf - d) x d the values of alphabets........... = 3.2 x 5 - (1.5 - 3) x 3 = 6 x 5 - (5 - 3) x 3 = 30 - 6 = 24 = 2 + 4 = 6 = bcc

Question 17

In a certain code PATHOLOGIST is written as PIUBQKSRHFN. How is CONTROVERSY written in that code?

Accepted Answer

Five letters of the word PATHOLOGIST are reversed first and then coded as one place forward. Similarly, the last five letters of the word are reversed then coded as one place backward. Middle letter is coded as one place backward. Hence, CONTROVERSY will be written as SUOPDNXRQDU.

Question 18

The following small letters are coded by capital letters in a certain way : s u m l a d R A P M S O Now, which small letters can be decoded from the letters given below : M A P S R O

Accepted Answer

According to given question, R = s A = u P = m M = l S = a O = d Replace the each capital from given relationship for M A P S R O, We will get M → l A → u P → m S → a R → s O → d

Question 19

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 letter may be indicated from the given responses. YMLOSBCI

Accepted Answer

we can write the given word YMLOSBCI as - Y → 1 M → 2 L → 3 O → 4 S → 5 B → 6 C → 7 I → 8 Arrange the words for the given option one by one. Arranging to meaningful word, we get S → 5 Y → 1 M → 2 B → 6 O → 4 L → 3 I → 8 C → 7 Hence , the correct option is B.

Question 20

Unscramble the following letters to frame a meaningful word and find out the correct numerical sequence of the letters. E → 1 S → 2 R → 3 T → 4 A → 5 R → 6 U → 7 N → 8 A → 9 T → 10

Accepted Answer

The below pattern is given in the question, E → 1 S → 2 R → 3 T → 4 A → 5 R → 6 U → 7 N → 8 A → 9 T → 10 Try all option one by one and formed a word by arranging them. After arranging the option (b), we get the meaningful word - R → 3 E → 1 S → 2 T → 4 A → 5 U → 7 R → 6 A → 9 N → 8 T → 10 Hence , the required answer will be Restaurant.
