Answer the following questions based on the alphabet given 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

Question 1:Â If the alphabets are written in reverse order after interchanging alphabets from â€˜D to Lâ€™ with those from â€˜R to Zâ€™ respectively, which letter would be midway between W and E in the new order ?

a)Â Z

b)Â N

c)Â L

d)Â There is no such letter

e)Â None of these

Solution:

AlphabetsÂ :Â 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

After interchanging alphabets from â€˜D to Lâ€™ with those from â€˜R to Zâ€™ respectively, thenÂ :

= A B C R S T U V W X Y Z M N O P Q D E F G H I J K L

Letter which is midway between W and E =Â N

=> Ans – (B)

Question 2:Â What will come in the place of question (?) mark in the following series ?
GPW, GPUW, GIPUW, GIPSUW, ?

a)Â GIHPSUW

b)Â GIPQSUW

c)Â GIKPSUW

d)Â GIJPSUV

e)Â None of these

Solution:

SeriesÂ :Â GPW, GPUW, GIPUW, GIPSUW, ?

We are adding one letter from the backÂ series, and similarly, adding one letterÂ from the front side.Â

EgÂ :- In 2nd term, U is added at the second last position and in the next term after that I is added at 2nd position from front. Thus, in the missing term, a new letter is added at 3rd position from front.

Thus, missing term =Â GIKPSUW

=> Ans – (C)

Question 3:Â If the letters of the word PRODUCTIVE which are at the odd numbered position in the English alphabet are picked up and rearranged in alphabetical order from left and if they are now substituted by Z, Y, X and so on, beginning from left which letter will get substituted by W ?

a)Â No letter will get substituted by W

b)Â O

c)Â E

d)Â C

e)Â None of these

Solution:

Word –Â PRODUCTIVE

Letters at odd numbered position in English alphabet = O,U,C,I,E

Arranging letters in alphabetical order = CEIOU

Substituting the letters, we get : ZYXWV

Thus, OÂ will get substituted by W.

=> Ans – (B)

Question 4:Â In the following set of numbers if â€˜1â€™ is added to the last digit of and then the order of digits is reversed ,which of the following will be the fourth if arranged in the ascending order 567 284 696 865 738

a)Â 567

b)Â 284

c)Â 696

d)Â 865

e)Â 738

Solution:

NumbersÂ : 567 284 696 865 738

IfÂ â€˜1â€™ is added to the last digit, then numbers :Â 568 , 285 , 697 , 866 , 739

Now, order of digits is reversed, = 865 , 582 , 796 , 668 , 937

After arranging in ascending order = 582 , 668 , 796 , 865 , 937

Thus, 4th from left = $865\equiv567$

=> Ans – (A)

Question 5:Â How many such pairs of letters are there in the word PHYSICAL each of which has as many letters between them in the word as apperar in the English alphabets.

a)Â None

b)Â One

c)Â Two

d)Â Three

e)Â More than three

Solution:

Word – ‘PHYSICAL’

There are 2 pairs of letters which have as many letters between them in the word as they have between them in the English alphabetical series

= (P,S) , (I,L)

=> Ans – (C)

Question 6:Â Four of the following are like in certain way on the basis of their positions in English alphabets and so form a group.which of the following does not belong to that group ?

a)Â HJG

b)Â PQN

c)Â DEB

d)Â TUR

e)Â KLI

Solution:

(A) : HÂ (+2 letters) = J (-3 letters) = G

(B) : P (+1 letter) = Q (-3 letters) = N

(C) : DÂ (+1 letter) = E (-3 letters) = B

(D) : TÂ (+1 letter) = U (-3 letters) = R

(E) : KÂ (+1 letter) = L (-3 letters) = I

=> Ans – (A)

TakeÂ  SNAP mock tests here

Question 7:Â What should come next in the following letter series ?
AN CQ ET GW ?

a)Â JZ

b)Â IZ

c)Â IY

d)Â KA

e)Â LZ

Solution:

Series :Â AN CQ ET GW ?

The pattern followed in each letter of the terms isÂ :

1st letter : A (+2 letters) = CÂ (+2 letters) =Â EÂ (+2 letters) =Â GÂ (+2 letters) =Â I

2nd letterÂ : NÂ (+3 letters) =Â QÂ (+3 letters) =Â TÂ (+3 letters) =Â WÂ (+3 letters) =Â Z

Thus, missing term =Â IZ

=> Ans – (B)

Question 8:Â Four of the following five are alike in a certain way (based on their positions of alphabets in the English alphabetical series) and hence form a group. Which is the one that does not belong to that group?

a)Â BFD

b)Â EIH

c)Â KOM

d)Â TXV

e)Â LPN

Solution:

BCDEF = BFD (1st -5th-3rd)

KLMNO = KOM(1st -5th-3rd)

TUVWX = TXVÂ (1st -5th-3rd)

LMNOP = LPN(1st -5th-3rd)

EFGHI = it should be EIG but it is given as EIH and hence this is the odd one out

Question 9:Â The sum of the squares of two odd numbers is 11570. The square of the smaller number is 5329. What is the other number?

a)Â 73

b)Â 75

c)Â 78

d)Â 79

e)Â 80

Solution:

let the two numbers be a and b , where b is the smaller number

$(a)^2$ + $(b)^2$ = 11570

$(a)^2$ + 5329 = 11570

$(a)^2$ = 6241 = 79 x 79

a = 79

Hence option D is correct

c)Â BUT

d)Â AND

e)Â SAW

Solution:

the given words areÂ Â RAT ONE BUT AND SAW

arranging alphabetically

AND BUT ONE RAT SAW

and hence fourth word from left side = RAT

Only 2Â meaningful word will be formed.

=> Ans – (B)

Question 12:Â If in the given words only consonants are changed with their successive letters and vowels are kept same then in how many words the vowel same or different will come twice or more than two times?

a)Â None

b)Â One

c)Â Two

d)Â Three

e)Â Four

Solution:

Words : RAT ONE BUT AND SAW

IfÂ only consonants are changed with their successive letters and vowels are kept sameÂ , then new wordsÂ :

a)Â One

b)Â Two

c)Â Three

d)Â Four

e)Â Five

Solution:

Words : RAT ONE BUT AND SAW

IfÂ each alphabet is changed to the next letter in to English alphabetical series, then new wordsÂ :

SBU , POF , CVU , BOE , TBX

Thus, in 4Â words thus formed the consonantsÂ have changed to vowels.

=> Ans – (D)
