The logic follows here is:

Thus, using the corresponding codes :

Hence, the correct answer is "24153".

The unfolded paper shown below,

Hence, the correct answer is "Option (1)".

The logic is:

1) 6932 – 150 → (6 + 9) × (3 + 2) × 2 = 150

2) 7851 – 180 → (7 + 8) × (5 + 1) × 2 = 180

3) 3712 – 60 → (3 + 7) × (1 + 2) × 2 = 60

4) 2134 – 40 → (2 + 1) × (3 + 4) × 2= 42 ≠ 40

Hence, ‘2134 – 40’ is the odd one out.

Given:

A and B were at the corners.

G and E were diagonally opposite each other.

F sits exactly between A and E facing east.

H was in front of F who was seated immediate right of A.

D was exactly between B and E.

So, "C" was sitting immediate left of A.

Hence, the correct answer is "C".

Given:

Expression:- V & W # T @ X % Y $ Z

Here,

V & W means V is the son of W.

W # T means W is the father of T.

T @ X means T is the brother of X.

X % Y means X is the sister of Y.

Y $ Z means Y is the daughter of Z

Thus, the following family tree can be drawn:

W is the husband of Z.

Hence, the correct answer is Husband.

The logic followed here is given below,

Hence, the correct answer is "2553".

Here the pattern followed in each row is:

(1^st number – 2^nd number) × 5 = 3^rd number

Row 1: 12 - 3 = 9 → 9 × 5 = 45

Row 2: 18 - 12 = 6 → 6 × 5 = 30

Similarly,

Row 3: 6 - 2 = 4 → 4 × 5 = 20

Hence, “20” is correct answer.

Logic : In each figure the enclosing figure is a quadrilateral (i.e the number of sides is four).

So,

• Option - (1) :

• Option - (4) :

BODMAS Table:

Given equation I: 4  × 3 - 7 + 8 ÷ 2 = 23

Now, if '7 and 4' are interchanged, then:

⇒ 7 × 3 - 4 + 8 ÷ 2 = 23

⇒ 7 × 3 - 4 + 4 = 23

⇒ 21 - 4 + 4 = 23

⇒ 25 - 4 = 23

⇒ 21 ≠ 23.

LHS ≠ RHS.

Given equation II: 7 × 5 - 9 ÷ 3 + 4 = 24

Now, if '7 and 4' are interchanged, then:

⇒ 4 × 5 - 9 ÷ 3 + 7 = 24

⇒ 4 × 5 - 3 + 7 = 24

⇒ 20 - 3 + 7 = 24

⇒ 27 - 3 = 24

⇒ 24 = 24

LHS = RHS.

Here, Only 'Equation I' are incorrect after interchanging the given symbol.

Hence, the correct answer is "Option 3".

The logic followed here is

Hence, the correct answer is "Option 4".
