(c) Y
(d) Z
Ans. (b) The required region is the one which is common to the circle and the rectangle but lies outside the triangle i.e. X.
Directions (Q.6-7): Each of the following questions is based on the following alphabet-series:
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
6. If the order of the English alphabet is reversed, then which letter would be exactly in the middle?
(a) L
(b) M
(c) N
(d) None of these
Ans. (d) The new letter-series obtained on reversing the order of the English alphabet is:
Z Y X W V U T S R Q P O N M L K J I H G F E D C B A
Since the series has an even number of letter (i.e. 26) there is no such letter which lies exactly
in the middle.
7. If the alphabet is written in the reverse order and every alternate letter starting with Y is dropped, which letter will be exactly in the middle of the remaining letters of the alphabet?
(a) M
(b) N
(c) O
(d) M or O
Ans. (b) Writing the given alphabet in reverse order, we have :
Z Y X W V U T S R Q P O N M L K J I H G F E D C B A
Cancelling every second letter, the new series becomes:
Z X V T R P N L J H F D B
There are 13 letters in the above series. So, the middle letter is the seventh letter i.e. N.
8. How many A’s are there in the following series which are immediately followed by B as well as immediately preceded by Z?
A M B Z A N A A B Z A B A Z B A P Z A B A Z A B
(a) Nil
(b) One
(c) Two
(d) Three
Ans. (d) A M B Z A N A A B Z  A  B A Z B A P Z  A  B A Z  A   B

9. In the given series of letters, how many t’s are preceded and followed by t?
P t P t t P P t P t P PP q q P t P t t P PP t
(a) 0
(b) 2
(c) 3
(d) 4
Ans. (a) Since there are no three t’s in consecutive order, so no such ‘t’ can be found.

10. How many L’s are there which do not have R preceding them and also do not have T following them?
Z Q S T L R M N Q N R T U V X R L T A S L T Q R S L T
(a) 1
(b) 2
(c) 3
(d) 5
Ans. (a) Z Q S T L R M N Q N R T U V X R L T A S L T Q R S L T
11. If \$ means +, # means –, @ means × and * means ÷, then what is the value of
16 \$ 4 @ 5 # 72 * 8 ?
(a) 25
(b) 27
(c) 29
(d) 36
Ans. (b) Using the correct symbols, we have:
Given expression = 16 + 4 × 5 – 72 ÷ 8 = 16 + 20 – 9 =36 – 9 = 27.
12. If P denotes ÷, Q denotes ×, R denotes + and S denotes –, then what is the value of
18 Q 12 P 4 R 5 S 6 ?
(a) 53
(b) 59
(c) 63
(d) 65
Ans. (a) Using the correct symbols, we have:
Given expression = 18 × 12 ÷ 4 + 5 – 6 = 18 × 3 + 5 – 6
= 54 + 5 – 6 = 59 – 6 = 53.
13.If ‘when’ means ‘×’, ‘you’ means ‘÷’, ‘come’ means ‘–’ and ‘will’ means ‘+’, then what will be the value of “8 when 12 will 16 you 2 come 10”?
(a) 45
(b) 94
(c) 96
(d) 112
Ans. (b) Using the correct symbols, we have:
Given expression = 8 ×12 + 16 ÷ 2 – 10 = 96 + 8 – 10
= 104 – 10 = 94.
14. If ‘+’ stands for ‘division’, ‘÷’ stands for ‘multiplication’, ‘×’ stands for ‘subtraction’ and ‘–’ stands for ‘addition’, which one of the following is correct?
(a) 18 ÷ 6 × 7 + 5 – 2 = 22
(b) 18 × 6 + 7 ÷ 5 – 2 = 16
(c) 18 ÷ 6 – 7 + 5 × 2 = 20
(d) 18 + 6 ÷ 7 × 5 – 2 = 18
Ans. (d) Using the proper notations in (d), we get the statement as:
18 ÷ 6 × 7 – 5 + 2 = 3 × 7 – 5 + 2 = 21 – 5 + 2 = 18.
15. If – means ÷, + means ×, ÷ means –, × means +, then which of the following equation is correct?
(a) 52 ÷ 4 + 5 × 8 – 2 = 36
(b)43 × 7 ÷ 5 + 4 – 8 = 25
(c) 36 × 4 – 12 + 5 ÷ 3 = 420
(d)36 – 12 × 6 ÷ 3 + 4 = 60
Ans. (a) Using the proper notations in (a), we get the statement as:
52 – 4 ×5 + 8 ÷ 2 = 52 – 4 × 5 + 4 = 52 – 20 + 4 = 56 – 20 = 36.
