16,25,43,70,106 ?
155
153
149
151
Correct answer
151
Why this answer is correct
Logic: Diffrences are increasing by +9 each time: +9, +18, +27, +36,.....
25 - 16 = 9
43 - 25 = 18
70 - 43 = 27
106 - 70 = 36
Next: 36 + 9 = 45
106 + 45 = 151
Hence, the correct answer is "Option 4"
In a certain code language,
A + B means 'A is the sister of B',
A@B means 'A is the brother of B',
A# B means 'A is the wife of B',
and A ÷ B means 'A is the father of B'.
How is W related to U if 'W@E+R÷H#U'?
Wife's father's brother
Wife's brother
Wife's father
Wife's father's father
Correct answer
Wife's father's brother
Why this answer is correct
Given :
| A is | ||||
|---|---|---|---|---|
| Symbol | + | @ | # | ÷ |
| Meaning | Sister | Brother | Wife | Father |
| to B |
'W@E+R÷H#U'
Hence, the correct answer is "Option 1"
Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
No hills are mountains.
Some mountains are valleys.
All valleys are glaciers.
Conclusions:
(I) No hills are valleys.
(II) Some mountains are glaciers.
Neither conclusion (I) nor (II) follows.
Both conclusions (I) and (II) follow.
Only conclusion (I) follows.
Only conclusion (II) follows.
Correct answer
Only conclusion (II) follows.
Why this answer is correct
The least possible Venn diagram for the given statements is as shown below :
Conclusions:
(I) No hills are valleys. - False ( Their is no direct relation between hills and valleys may be possible but not definite. Hence, it is false)
(II) Some mountains are glaciers.- True (Some mountains are valleys.All valleys are glaciers.Some mountains are glaciers is True)
Only conclusion (II) follows.
Hence, the correct answer is "Option 4".
In a certain code language, 'are you here' is written as 'yg ko ws' and 'you were right' is coded as 'ws hj lk'. How is 'you' coded in that language?
lk
ws
hj
ko
Correct answer
ws
Why this answer is correct
The logic follows here,
Hence, the correct answer is "Option 2"
What should come in place of the question mark (?) in the given series?
4 13 25 76 151 ?
454
445
435
473
Correct answer
454
Why this answer is correct
The logic follows here,
The pattern alternates between ×3 +1 and ×2 −1
4 × 3 + 1 = 13
13 × 2 − 1 = 25
25 × 3 + 1 = 76
76 × 2 − 1 = 151
Next should follow ×3 +1
151 × 3 + 1 = 454
Hence, the correct answer is "Option 1"
A, B, C, D, J, K and L are sitting around a circular table facing the centre of the table.
D sits third to the left of L. A sits second to the left of K. L is an immediate neighbour of both B and A. C is not an immediate neighbour of D.
How many people sit between J and A when counted from the right of J?
Three
One
Two
Four
Correct answer
Two
Why this answer is correct
A, B, C, D, J, K and L are sitting around a circular table facing the centre of the table.
The Final Arrangement is ,
Hence, the correct answer is "Option 3"
RX 2 is related to TT -7 in a certain way. In the same way, MQ 9 is related to OM 0. To which of the following is NV 15 related, following the same logic?
QR 8
PR 6
PQ 8
QQ 6
Correct answer
PR 6
Why this answer is correct
The logic followed here is:
Hence, the correct answer is "Option 2"
Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - Operations on 13 such as adding to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(11,18,396)
(19,12,456)
(13,14,364)
(15,11,380)
(17,13,441)
(16,10,330)
Correct answer
(13,14,364)
Why this answer is correct
Logic : 2 x First Number x Second Number = Third Number
For (11, 18, 396):
2 × 11 × 18 = 396
For (19, 12, 456):
2 × 19 × 12 = 456
Similarly,
(13,14,364)
2 × 13 × 14 = 364
Hence, the correct answer is "Option 1"
Refer to the following number series and answer the question that follows (all numbers are single-digit numbers only). Counting to be done from left to right only.
(Left) 4 7 1 9 0 5 3 8 2 6 1 4 7 9 2 0 3 6 8 5 1 2 7 3 4 (Right)
How many of the numbers are perfect squares?
Eight
Five
Twelve
Ten
Correct answer
Eight
Why this answer is correct
Given (Left) 4 7 1 9 0 5 3 8 2 6 1 4 7 9 2 0 3 6 8 5 1 2 7 3 4 (Right)
Required Conditions : perfect squares
(Left) 4 7 1 9 0 5 3 8 2 6 1 4 7 9 2 0 3 6 8 5 1 2 7 3 4 (Right)
Hence, the correct answer is "Option 1"

B
C
A
Correct answer
C
Why this answer is correct
A, B, C, D and E have different ages. C is older than B but younger than D. Only one person is younger than A. B is not the youngest.
Hence, the correct answer is "Option 3"
