Given series: 3 6 17 2 4 8 13 12 14 1 3 6 19

After deleting even numbers:

3 17 13 1 3 19

Here, 4^th from the right is 13 when even numbers from the series are deleted.

Hence, 13 is the correct alternative.

Given word:

Left 'DISCOUNT' Right

Arranging the letters of the given word in alphabetical order:

There is only one alphabet i.e. O whose position remains unchanged after the arrangement.

Hence, the correct answer is "One".

The positional value of alphabets is;

Given series;

GO, KM, OK, SI, ? 

The pattern follows in given series is;

Hence, the correct answer is "WG".

Preparing the family tree using the following symbol:

Family Tree :-

1) Aakash is the brother of Riva and father of Vansh and Ritu.

2) Ritu is the only daughter of Aakash and Maya.

• This means Ritu is female as she is the only daughter of Maya and Aakash. Thus Vansh will be male.

3) Mahesh is the father of Riva and paternal grandfather of Vansh.

∴ Here, Maya is the 'Daughter-in-law' of Mahesh.

Hence, the correct answer is "Daughter-in-law".

The pattern followed here is,

Similarly,

Hence, “UIGJO” is the correct answer.

The logic followed here is :- 

1. First and third letters → (2) is subtracted from the position value according to English alphabetic series.
2. Second letter → (3) is added to the position value according to English alphabetic series.

​So,

• = BNQ, % = NFM ⇒ BNQ : DKR :: PCL: NFM

​

⇒Here, no similar pattern can be seen.

• = FHT, % = NFJ ⇒ FHT : DKR :: PCL: NFJ

​

⇒Here, similar pattern can be seen.

• = COQ, % = OGH ⇒ COQ : DKR :: PCL: OGH

​

⇒Here, no similar pattern can be seen.

• = BNP, % = NFJ ⇒ BNP : DKR :: PCL: NFJ

​

⇒Here, no similar pattern can be seen.

Hence, the correct answer is "Option - (2)".

Six tables - C, D, L, N, P and X (facing towards the south)

1. D is placed second to the left of L.

2. N is placed third to the left of D.

3. X is placed second to the right of P.

After combining statements (1), (2) and (3), we get:

Now, only ‘C’ is left and hence ‘C’ will occupy the vacant position. So, the final arrangement is:

Hence, ‘two’ tables are placed between C and X.

The mirror image of the figure when the mirror is kept on the MN line is shown below:

Hence, ‘option 3’ is the correct answer.

Here the logic is:

Hence, 50 is the correct answer.

Given Statements:

All paper are chair.

Same chair are ground.

All cat are ground.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some cat are chair - False (Because, No definite relation given between cat and chair, so it can be possible only).

II. Some chair are not paper - False (Because, All paper are chair gives some chair are paper, So, some chair are not paper will be true in possibility only).

So, Neither conclusion I nor II follows .

Hence, the correct answer is "Option 4".
