Instructions
In each of the following questions two rows of numbers are given. The resultant number in each row is to be worked out separately based on the following rules and the questions below the rows of numbers are to be answered. The operations of numbers progress from left to right.
Rules:
(a) If an odd number is followed by a two digit even number then they are to be added.
(b) If an odd number is followed by a two digit odd number then the second number is to be subtracted from the first number.
(c) If an even number is followed by a number which is a perfect square of a number then the second number is to be divided by the first number.
(d) If an even number is followed by a two digit even number then he first number is to be multiplied by the second number.
Question 9: 15 11 20 400
8 12 10
If the resultant of the second set of a numbers is divided by the resultant of the first set of numbers what will be the outcome ?
a) 192
b) 200
c) 19
d) 92
e) None of these
Question 10: What should come next in the following letter series ?
PQRSTABCDEPQRSABCDEPQRSABCDPQ
a) R
b) T
c) A
d) B
e) None of these
Answers & Solutions:
1) Answer (E)
40 R 8 W 10 T 12 P 16 means 40$\div$8×10-12+16.
Now, going by BODMAS rule, we first divide and then multiply.
40/8=5, 5*10=50, 50-12=38, 38+16=54
Here, none of the options is 54.
Therefore, the correct answer is option E.
2) Answer (B)
Alphabets : 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 ‘D to L’ with those from ‘R to Z’ respectively, then :
= 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 = N
=> Ans – (B)
3) Answer (C)
Lets write the original and rearranged number one below the other 59164823
98654321
So we can see that numbers whose place remains unchanged are 2 and 4, Thus the answer is 2
4) Answer (B)
Word – 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, O will get substituted by W.
=> Ans – (B)
5) Answer (E)
So, the question essentially asks to find out pairs of letters in the given word “EXECUTION” which have same number of letter between them as there are in english alphabet. We can start with the first letter initially and then try to check for subsequent letters. Lets take E now EX have 18 letter between them in english alphabets, here they don’t have any letter so this cannot be a possible pair. Lets move on to EE which is again not possible. EC have just 2 letters between them which is not the case in actual english alphabets. Proceeding in a similar manner we can find that words fulfilling the given requirement are
XU, XT,EI,UT. Since we have figured out the 4 words already, the only feasible option is Option 5

6) Answer (D)
Words : RAT ONE BUT AND SAW
If each alphabet is changed to the next letter in to English alphabetical series, then new words :
SBU , POF , CVU , BOE , TBX
Thus, in 4 words thus formed the consonants have changed to vowels.
=> Ans – (D)
7) Answer (A)
There are 21 characters between F and B. So, the middle character is the 11th character to the right of F. This is P.
So, option a) is the correct answer.
8) Answer (A)
Arrangement : 1 5 8 4 2 1 5 2 3 4 5 6 7 8 9 5 1 4 1 5 6 8 7 4
If all the even digits are deleted, then
= 1 5 1 5 3 5 7 9 5 1 1 5 7
10th from right end = 5
=> Ans – (A)
9) Answer (A)
For the first set of numbers, 15 11 20 400
Using rule no.2 for first 2 numbers we get
4 20 400
Now using rule no. 4 we get, 4*20 = 80, so sequence becomes
80 400
Now by using rule no. 3 we get, 400/80 = 5
For the second set of numbers, 8 12 10
Applying rule no. 4 we get, 8*12 = 96
96 10, Again by using rule no. 4 we get,
960
Now dividing the resultant of 2nd sequence by resultant of first sequence gives,
960/5 = 192
10) Answer (A)
The above series is the combination of two series i.e. :
PQRST & ABCDE
After that, last alphabet of the first series is removed => PQRS & ABCDE
Then ,the last alphabet of the second series is removed => PQRS & ABCD
After that, S should be removed => PQR & ABCD
Clearly, the next letter is R.
