Question 1
1 / -0

In each of the following questions, therefore are four options. The numbers, in these options, are alike in certain manner. Only one number does not fit in. Choose the one which is different from the rest.

A
$$1472$$

B
$$3848$$

C
$$2683$$

D
$$4210$$

Solution

In all the numbers except 2683, the digit 4 is used. Hence, the odd one is option C.
Question 2
1 / -0

In each of the following questions, therefore are four options. The numbers, in these options, are alike in certain manner. Only one number does not fit in. Choose the one which is different from the rest.

A
$$9$$

B
$$7$$

C
$$12$$

D
$$18$$

Solution

All except the number 7 are multiples of 3. Hence, the odd one is option B.
Question 3
1 / -0

In each of the following questions, therefore are four options. The numbers, in these options, are alike in certain manner. Only one number does not fit in. Choose the one which is different from the rest.

A
$$24$$

B
$$90$$

C
$$54$$

D
$$36$$

Solution

All except the number 24 are multiples of 9. Hence, the odd one is option A.
Question 4
1 / -0

In each of the following questions, therefore are four options. The numbers, in these options, are alike in certain manner. Only one number does not fit in. Choose the one which is different from the rest.

A
$$325$$

B
$$207$$

C
$$711$$

D
$$423$$

Solution

All numbers except 325 have the sum of the numbers of their digits as 9. Hence, the odd one is option A.
Question 5
1 / -0

In each of the following questions, therefore are four options. The numbers, in these options, are alike in certain manner. Only one number does not fit in. Choose the one which is different from the rest.

A
$$43$$

B
$$53$$

C
$$63$$

D
$$73$$

Solution

All except the number 63 are prime numbers. Hence, the odd one is option C.
Question 6
1 / -0

Four numbers are given below, out of which three are alike in some manner and fourth is different. Choose the different number :

A
$$11$$

B
$$13$$

C
$$15$$

D
$$17$$

Solution

Except option C, all are prime numbers.
Hence that's the odd one out.
Question 7
1 / -0

In each of the following questions, therefore are four options. The numbers, in these options, are alike in certain manner. Only one number does not fit in. Choose the one which is different from the rest.

A
$$49$$

B
$$97$$

C
$$98$$

D
$$77$$

Solution

All except the number 97 are multiples of 7. Hence, the odd one is option B.
Question 8
1 / -0

In certain code PAPER is written as SCTGW, how will MOTHER written in that code ?

A
ORVLGW

B
PQVJGT

C
PQXJJT

D
PQXJGT

Solution

Here there are 2 patterns to be observed on the 2 sets of alternating alphabets
The first set of alternating alphabets are $$P,P,R$$ from $$PAPER$$
The second set of alternating alphabets are $$A,E$$ from $$PAPER$$
In the first set, the code is formed by a pattern of skipping alphabets progressively.
For example in the first set $$P,P,R$$,
The first $$P$$ is coded as $$S$$ after skipping $$2$$ alphabets ($$ Q , R$$)
The second $$P$$ is coded as $$T$$ after skipping $$3$$ alphabets ($$Q, R, S$$)
The $$R$$ is coded as $$W$$ after skipping $$4$$ alphabets ($$S,T,U, V$$)
In the second set, the code is formed by a pattern of skipping only $$1$$ alphabet.
For example, in the second set $$A,E$$
$$A$$ is coded as $$C$$ after skipping $$1$$ alphabet ($$ B$$)
$$E$$ is coded as $$G$$ after skipping $$1$$ alphabet ($$ F$$)
We need to separate the word $$MOTHER$$ from the question into 2 sets of alphabets
$$\rightarrow$$ The first set being $$M,T,E$$
$$\rightarrow$$ The second set being $$O,H, R$$
Similar to the above pattern the first set ($$M,T,E$$) needs to be coded by a pattern of skipping alphabets progressively
$$\rightarrow$$ $$M$$ gets coded as $$P$$ (by skipping 2 alphabets $$N,O$$)
$$\rightarrow$$ $$T$$ gets coded as $$X$$ (by skipping 3 alphabets $$U,V,W$$)
$$\rightarrow$$ $$E$$ gets coded as $$J$$ (by skipping 4 alphabets $$F,G,H,I$$)
The second pattern ($$O,H, R$$) is coded by skipping only $$1$$ alphabet all the time
$$\rightarrow$$ $$O$$ is coded as $$Q$$ after skipping $$1$$ alphabet ($$ P$$)
$$\rightarrow$$ $$H$$ is coded as $$J$$ after skipping $$1$$ alphabet ($$ I $$)
$$\rightarrow$$ $$R$$ is coded as $$T$$ after skipping $$1$$ alphabet ($$ S$$)
So, the word $$MOTHER$$ gets coded as $$PQXJJT$$, which is option $$C$$
Question 9
1 / -0

In each of the following questions, therefore are four options. The numbers, in these options, are alike in certain manner. Only one number does not fit in. Choose the one which is different from the rest.

A
$$4756$$

B
$$2074$$

C
$$6572$$

D
$$4677$$

Solution

No number is repeated in any of the given numbers except 4677. Hence, the odd one is option D.
Question 10
1 / -0

Four numbers are given below out of which three are alike in some manner and fourth is different. Choose the different number :

A
$$144$$

B
$$168$$

C
$$196$$

D
$$256$$

Solution

All are perfect squares except $$168$$
Hence, option B is the odd one out.
