A = Z .....this is one behind A
R = T .....THIS Is two ahead of R
V = T.......This is two behind V
A = D .....This is 3 ahead of A
R = O .....This is 3 behind R
D = H .....This is 4 ahead of D
W = X One ahead of W
H =G One behind H
and so on you should get the answer as option A

20. If REQUEST is written as S2R52TU, how will you write
ACID ?
(a) BDJE (b) 1394 © B3J4 (d) 1D3E

Solution :

R=S one ahead of R , E =2 this is the second vowel of the english alphabet hence codded as 2; Q=R one ahead of Q, U is the 5th vowel of English alphabet and hence coded as 5.; S and T are not vowels hence coded as letters one ahead i.e. T and U respectively.
The correct answer for ACID = 1D3E - Option d

42. A compass had been damaged ( in an accident) and its
needle turned in such a manner that the pointer which
was showing west, started showing south. One person
went in the wrong direction on the basis of the compass
thinking it to be east. In what direction is he actually
travelling ?
(a) South (b) West © North (d) East

Solution :
What you need to understand here is that the pointer is still showing west , but the direction is South. So on the compass it appears to be West and the actual direction is changed anticlockwise by 90 degrees. Therefore if the direction shown on the compass is East, the actual direction should be anticlockwise 90 degrees from East , i.e. - North

72. If 42 + 60 = 36 and 79 + 28 = 160, then what is the value
of 249 + 63 ?
(a) 369 (b) 162 © 135 (d) None of these

Solution
42 + 60 =36 in this case the sum of digits of 42 =6, when multiplied with the sum of digits of 60 = 6 gives the result 36. Similarly the sum of digits of 79 = 16 when multiplied with sum of digits of 28 =10 gives the result 160.
Therefore for 249 + 63 = 15 x 9 =135
Answer option C

75. If “SQUARE” = 87 and “RECTANGLE” = 94, then what is
the value of ROMBUS ?
(a) 96 (b) 94 © 89 (d) None of these

Solution:
In the above question you add up the rank of the letter in the alphabet and add the ranks. To the added rank you add the number of letters that make the word. For example in the word "SQUARE" , the ranks of
S =19, Q =17, U= 21 , A=1, R=18, E=5 - the addition of all the ranks gives the result 81 AND TO it if you add the number of letters that make the word "SQUARE" i.e. if you add 6 to 81 we get

81 + 6 =87 .
Similarly if you do the same for the word "RECTANGLE: YOU get the result as 94; For the word ROMBUS - The ranks of the respective letters are 18,15,13,2,21,19 in that order which add up to 88.

88 + 6 (number of letters in the word ROMBUS) =94
Answer option b
