Question 1
1 / -0

If M is Father of N, L is Brother of M and P is Mother of L, then what is the relation of N with P ?

A
Grand-Daughter

B
Grand-Son

C
Father

D
Data inadequate

Solution

From the given information, we can conclude that:
P has two son M and L.
M is father of N.
So, N may be the grand son/grand daughter of P.
option D
Question 2
1 / -0

Select the odd one from the given series:
$$3, 7, 9, 21, 27, 66, 81, 189, 243$$

A
$$27$$

B
$$66$$

C
$$243$$

D
$$21$$

Solution

Given series is: $$3, 7, 9, 21, 27, 66, 81, 189, 243$$
There are two alternate series :
Series I : $$3, 9, 27, 81, 243$$
Series II : $$7, 21, 66, 189$$
In series I, each number is multiplied by $$3$$ to get the next number whereas in series II except $$66$$, all other numbers are obtained by multiplying previous number by $$3$$.
Also, $$63$$ should replace $$66$$.
Hence, option (B) is the correct.
Question 3
1 / -0

In a coded language FRUIT = HTWKV, then FLOWER will be written as -

A
HNQYGT

B
HGPTYN

C
HYNGPT

D
HTPNGY

Solution

Given, FRUIT = HTWKV. The coding pattern for the same is:
F $$\underrightarrow { +2\quad } $$ H
R $$\underrightarrow { +2\quad } $$ T
U $$\underrightarrow { +2\quad } $$ W
I $$\underrightarrow { +2\quad } $$ K
T $$\underrightarrow { +2\quad } $$ V
Similarly, FLOWER is coded as follows:
F $$\underrightarrow { +2\quad } $$ H
L $$\underrightarrow { +2\quad } $$ N
O $$\underrightarrow { +2\quad } $$ Q
W $$\underrightarrow { +2\quad } $$ Y
E $$\underrightarrow { +2\quad } $$ G
R $$\underrightarrow { +2\quad } $$ T
Hence, FLOWER is written as HNQYGT.
Therefore, option (A) is the correct answer.
Question 4
1 / -0

In the following question, four numbers/pairs are given out of which three are alike in some manner while one is different. Choose the one which is different from the rest three.

A
CADGE

B
JHKNL

C
ECFGI

D
XVYBZ

Solution

Every group of letters have certain pattern :
The letters at odd position are consecutive letters and the letters at even positions differ by $$+6$$.
But in option C, the letters at odd position are not consecutive.
Thus, it is different from others.
Hence, option C is correct.
Question 5
1 / -0

In the following question, four figures are given. One of these figures does not correlate with the rest of the figures. Find the different figure.

A

B

C

D

Solution

Option C is the correct answer.

Explanation

It is clearly visible that figure a,b and c have a cross cut with line ion one side in middle of pentagon but in figure of option C there is no cross and hence it is different from the rest.
Question 6
1 / -0

Find the number that does not belong to the group?
$$111,331,482,551,263,383,362,284$$

A
$$263$$

B
$$331$$

C
$$383$$

D
$$551$$

Solution

It follow a pattern :
$$1^{st}$$ digit $$\times$$ $$2^{nd}$$ digit =$$3^{rd}$$ digit i.e.
$$1\times 1=1$$, $$3\times 1=3$$, $$4\times 2=8$$, $$5\times 1=5$$,
$$2\times 3=6$$. But $$3\times 3=9$$ and the number given is $$383$$ instead of $$393$$.
Hence, $$383$$ is the number which does not belong to the group.
Question 7
1 / -0

In the following question, four numbers/pairs are given out of which three are alike in some manner while one is different. Choose the one which is different from the rest three.

A
SUXB

B
LNQU

C
BDGK

D
JLNQ

Solution

The letters in every word follow a difference pattern of $$+2,+3,+4$$ i.e.
S$$+2\rightarrow$$U, U$$+3\rightarrow$$X, X$$+4\rightarrow$$B.
Similarly for B and C.
But word in option D has a difference pattern $$+2,+2,+3$$.
Thus, it is different from others.
Hence, option D is correct.
Question 8
1 / -0

Out of the four words, three follows one pattern, while one is different. Choose the one which is different from the rest three.

A
ACEGF

B
FHJLK

C
KMOQP

D
UWYZA

Solution

Here, in each of the group, the second letter is two steps ahead of first letter, the third letter is two steps ahead of the second letter and the fourth letter is two steps ahead of the third letter and the fifth letter is one step back to the fourth letter, according to the English alphabet which is not the case with UWYZA.
Hence, option (D) is the correct answer.
Question 9
1 / -0

In the following question, four numbers/pairs are given out of which three are alike in some manner while one is different. Choose the one which is different from the rest three.

A
PROQN

B
DFCEG

C
GIFHE

D
KMJLI

Solution

Option B is the correct answer.

Explanation:
In the following series the first letter is moved two steps forward to form the second letter,
First letter moves one step backward to form the third letter,
Second letter is moved one step backward to form the fourth letter and
Third letter is moved one step backward to form the fifth letter.

Hence, DFCEG does not match the series.
Question 10
1 / -0

Find the odd term

A
$$4321$$

B
$$3212$$

C
$$2116$$

D
$$6211$$

Solution

All other except B, follow the pattern :
$$\Rightarrow$$ sum of digits $$= 10$$. i.e.
$$4+3+2+1=10$$
$$2+1+1+6=10$$
$$6+2+1+1=10$$
But in B, $$3+2+1+2=8$$.
Hence, option B is the odd term.
