As per the given information,

Step I:- F sits third to the right of B. D sits to the immediate left of B.

Here, three possible arrangement are drawn.

Step II:-  One person sits between C and D. D is not a neighbour of G.

Step III:- A sits second to the left of E.

Now, by seeing the final diagram

• The given statement says that this detergent cleans better than "other detergents" which means more than one detergents are present in the market.
• So the first assumption is implicit.
• The second assumption 'No other detergents clean better.' is implicit since the statement means that this detergent cleans better than "all" the others, thus there is no other detergent that cleans better than this one.
• So assumption II is also implicit.

Hence, option 4 is the correct answer.

According to the given information,

Statement (I): T is towards South of K which is towards West of P.

So,

Statement (II): R is towards South of V and towards East of T.

So,

Therefore, Data in statement I alone is sufficient to answer the question.

Hence, option 1 is the correct answer.

1) Packet A has price more than M but less than C

→ C > A > M

2) Packet B has price more than O but less than M

→ M > B > O

3) Packet N is the cheapest

On combining we get,

C > A > M > B > O > N

Hence, C is the costliest.

The position of the letters according to the English alphabet series,

WORC → 23 +15 + 18 + 3 = 59 (Odd)

ETIK → 5 + 20 +9 + 11 = 45 (Odd)

LUOS → 12 + 21 +15 +19 = 67 (Odd)

TGKL → 20 + 7 + 11 + 12 = 50 (Even)

Therefore, TGKL is odd from all.

Hence, the correct answer is "TGKL".

The table showing the positional value of the alphabets is as follows

Given series :-  OEST, QGQR, SIOP, ?, WMKL

Here, following code is used..

Therefore '?' will be replaced by 'UKMN'

Hence, the correct answer is option(1)

Given:

• + means −
• − means ×
• × means ÷
• ÷ means +

We need to find the value of the following expression:

5 ÷ 5 + 5 – 10 × 10

Substituting the given symbols, we get:

5 + 5 - 5 × 10 ÷ 10

= 5 + 5 - 5 × 1

= 5 + 5 - 5

= 10 - 5 

= 5

Therefore, the value of the expression is 5.

Hence the correct answer is " Option (3)."

The pattern followed here is:

Given: × and –, 8 and 4

After interchanging the sign and number we get the;

1) 4 + 3 × 8 – 2 ÷ 1 = 3

⇒ 8 + 3 - 4 × 2 ÷ 1 = 3

⇒ 8 + 3 - 4 × 2 = 3

⇒ 8 + 3 - 8 = 3

⇒ 11 - 8 = 3

⇒ 3 = 3 (This equation is correct)

2) 8 × 2 – 4 + 6 ÷ 2 = 11

⇒ 4 - 2 × 8 + 6 ÷ 2 = 11 

⇒ 4 - 2 × 8 + 3 = 11

⇒ 4 - 16 + 3 = 11

⇒ 7 - 16 = 11

⇒ - 9 ≠ 11 (This equation is not correct)

So, only the equation II is incorrect.

Hence, the correct answer is "Only II".

The logic in the matrix is Row wise as follows:

(Column1 × Column2) - 10 = Column3

Row1 : (7 × 13) - 10 = 91 - 10 = 81

Row2 : (15 × 9) - 10 = 135 - 10 = 125

Row3 : (18 × 14) - 10 = 252 - 10 = 242

So, the number in place of a question mark is 242.

Hence, the correct answer is "Option (3)".

The logic here used is:

Hence, the missing number is '129'.
