DIRECTIONS for questions 1-3: What should come in place of question mark (?) in the following number/alphabetic series.
12 34 54 71 84?
89
92
124
102
110
Answer: Option B.
The respective differences between the terms : 22, 20, 17, 13
The difference between differences : 2, 3, 4 & 5
=>The difference is 18 & the required no. = 84 + 8 = 92.
360 72 18 6 ? 3
3
5
4
4.5
6
Answer: Option A
The pattern is as follows:
360/5 = 72
72/4 = 18
18/3 = 6
=>6/2 = 3.
382 380 374 356 302?
212
240
140
201
158
Answer: Option C.
The pattern is as follows:
382 – 2 = 380
380 – 6 = 374
374 – 18 = 356
356 – 54 = 302
=>302 – 162 = 140.
DIRECTIONS for questions 4 to 6: The questions below has two/three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follow from the given statements disregarding commonly known facts.
If only (1) conclusion follows
If only (2) conclusion follows
If either (1) or (2) follows
If neither (1) nor (2) follows
If both (1) and (2) follow
Statements: All features are attributes. All attributes are traits. Conclusion I: All traits are attributes. Conclusion II: All features are traits
Answer: Option B
Statements: Some rates are prices. All prices are charges. Conclusion I: Atleast some rates are charges. Conclusion II: All charges are prices
Answer: Option A.
Conclusion I:Atleast some rates are charges, is true.
The pairs are made as: the first and the sixth, the second pair will be the preceding symbol to the sixth and the one which is fifth to it, the third pair will be the preceding symbol to the fifth and the one which is fourth to it, the fourth pair will be the preceding symbol to the fifth and the one which is third to it. Similarly, Next pair will be preceding symbol of Z which is @ and the one which is second to it. Therefore, @L will be next pair.
The following series is based on a particular combination of English alphabets and numbers. Which of the following will come in place of question mark (?) in the given series?
9Z-20 11A-18 13Y-16 15B-14?
14D-10
16B-12
17X-12
16X-10
17D-10
Answer: Option C.
9Z-20 11A-18 13Y-16 15B-14 ?
In this , first number of each Pair is increasing by 2 and the last number is decreasing by 2such as
9_ -20 , 11_-18 , 13_-16 15_-14 , so that next arrangement will be
15+2_- 14-2=> 17_-12
two series are appear as alternatively with alphabetical series and reverse alphabetical series, Such as
Z , A , Y , B Therefore, next letter will be X. Combining both numeric and alphabetical series the next pair will be = 17X-12
How many such pairs of digits are there in the number 31748296 (both in forward and backward directions), each of which has as many digits between them as in the arithmetic series?
Three
More than three
One
None
Two
Answer: Option E
There are only 2 pairs of digits in the number 31748296 having as many digits between them as in the arithmetic series and these are (3, 9) and (4, 2).
In a certain code language, 'send the tests' is coded as 'al vx se' and 'all tests solved' is coded as 'se pg nb'. How will 'tests' be coded as in the given code language? (Note-all codes are two letter codes only)
nb
vx
Either 'nb' or 'pg'
se
Either 'ol' or 'pg'
Answer: Option D
Given that 'send the tests' is coded as 'al vx se' and 'all tests solved' is coded as 'se pg nb'
Tests is common in both statements. From the comparison, it can be observed that ‘tests’ is coded as ‘se’ in the given code language.
