The logic followed here is:

Logic: This sequence represents the progression from the largest unit to the smallest unit. Chapters combine to make up a book, Multiple paragraphs form a chapter, Sentences are grouped to form paragraphs and Individual letters are used to form sentences.

The correct logical order is as follows:

5) Book

4) Chapter

3) Paragraph

1) Sentence

2) Letter

Hence, the correct answer is "5, 4, 3, 1, 2".

The mirror image of the given figure is shown below:

Hence, the correct answer is "Option 3".

The logic followed here is:

Option 1) ZWSH

Here, 'GDAZ' is odd among the given options.

Hence, the correct answer is "Option 4".

BODMAS Table:

Given equation I: 5 × 12 – 15 + 20 ÷ 30 = 7

Now, if '+ and ×' are interchanged, then:

⇒ 5 + 12 – 15 × 20 ÷ 30 = 7

⇒ 5 + 12 – 10 = 7

⇒ 17 - 10 = 7

= 7 = 7.

LHS = RHS.

Given equation II: 51 ÷ 17 × 9 + 10 – 8 = 85

Now, if '+ and ×' are interchanged, then:

⇒ 51 ÷ 17 + 9 × 10 – 8 = 85

⇒ 3 + 9 × 10 – 8 = 85

⇒ 3 + 90 – 8 = 85

⇒ 93 - 8 = 85

= 85 = 85

LHS = RHS.

Here, 'Both I and II' are the correct after interchanging the given symbol.

Hence, the correct answer is "Option 1".

When we unfold the paper step by step we get the following image:

Hence, the correct answer is "Option 3".

After interchanging 13 and 11, the equation we get:

→ 48 ÷ 6 + 9 – 13 × 13 + 11 =?

→ 8 + 9 – 13 × 13 + 11 =?

→ 8 + 9 – 169 + 11 =?

→ 28 – 169 =?

→ – 141 =?

Hence, the correct answer is "– 141".

As per the given statements,

1) U is elder than only four other sisters.

→ _ > _ > U > _ > _ > _ > _

2) X is elder than one person only that is Z who is the youngest among all sisters.

→ _ > _ > U > _ > _ > X > Z

3) T is elder than Y.

4) U is elder than T.

→ _ > _ > U > T > Y > X > Z

5) V is elder than W.

→ V > W > U > T > Y > X > Z

Here, we can see that V is the eldest sister.

Hence, the correct answer is "V".

The logic followed here is :-

• First and third letters → Interchanged their positions.
• Second and fourth letters → (1) is added to the position value according to the English alphabetic series.

​So,

• WIRE : RJWF

Similarly,

• IMLI : ?

Hence, the correct answer is "LNIJ".

The logic followed here is:

Given Sequence: n o _ m _ l _ o _ m _ l n _ r _ a l

Now, putting the letters in the blank spaces given in the option one by one:

Option 1) naromra → n o n m a l / r o o m m l / n r r a a l

Option 2) ranraom → n o r m a l / n o r m a l / n o r m a l

Option 3) noamrna → n o n m o l / a o m m r l / n n r a a l

Option 4) manrmao → n o m m a l / n o r m m l / n a r o a l

Here, 'Option 2' followed a pattern.

Hence, the correct answer is "Option 2".

The logic followed here is:

Option 1) IJK → I + 1 = J; J + 1 = K.

Option 2) GIK → G + 2 = I; I + 2 = K.

Option 3) LNP → L + 2 = N; N + 2 = P.

Option 4) TVX → T + 2 = V; V + 2 = X.

So, 'IJK' odd among the all options.

Hence, the correct answer is "Option 1".
