The logic followed here is:

1. Sarangi: The sarangi is a stringed instrument used mainly in Indian classical music.

2. Telephone: This is a communication device used for transmitting and receiving voice messages.

3. Saxophone: The saxophone is a woodwind instrument, usually made of brass, played by use of a single-reed mouthpiece.

4. Xylophone: A musical instrument in the percussion family that consists of wooden bars struck by mallets.

Here, "Sarangi," "Saxophone," and "Xylophone" are all musical instruments but "Telephone" is not a musical instrument.

Hence, the correct answer is " Telephone ".

In the given pair "Turtle : Reptile", a turtle is an example of a reptile. So, we need to find a pair where the second word is the class of the animal, and the first word is an example of that class.

Following this logic:

• "Snake : Rodent" is incorrect, as a snake is a reptile, not a rodent.
• "Mammal : Man" is incorrect, as according to the given format, the class (mammal) should be in the second place, not the first.
• "Lizard : Reptile" is correct, as a lizard is indeed an example of a reptile, which follows the same pattern.
• "Mammal : Frog" is incorrect, as a frog is an amphibian, not a mammal.

Therefore, the correct answer is "3) Lizard : Reptile".

The triangles are:

So, there are '13' triangles in the given figure.

Hence, the correct answer is "13".

Logic: Place value of Opposite letter - Positional value of given letter

‘BACK’ is coded as ‘2325215

B →  Y(25) - B(2) = 23

A →  Z(26) - A(1) = 25

C → X(24) - C(3) = 21

K → P(16) - K(11) = 5

‘CAME’ is coded as ‘2125117

C →  X(24) - C(3) = 21

A →  Z(26) - A(1) = 25

M →  N(14) - M(13) = 1

E  →  V(22) - E(5) = 17

Similarly,

G → T (20) - G (7) = 13

B → Y (25) - B (2) = 23

J →  Q(17) - J (10) = 7

H → S(19) - H (8) = 11

Hence, the correct answer is 1323711.

The logic followed here is:

Logic: 1st number ÷ 9 = 2nd number.

Now, checking the options:

Option 1) 28125 – 3125 → 28125 ÷ 9 = 3125.

Option 2) 11322 – 1258 → 11322 ÷ 9 = 1258.

Option 3) 49374 – 5483 → 49374 ÷ 9 = 5486 ≠ 5483.

Option 4) 49401 – 5489 → 49401 ÷ 9 = 5489.

So, '49374 – 5483' odd among the given options.

Hence, the correct answer is "Option 3".

The logic followed here is:

Option 1) QNJF

The logic followed here is

1. Scooter - Vehicle: This pair represents a general category and a specific item within that category. A scooter is a type of vehicle, so this pair is consistent and does not stand out as odd.

2. Triangle - Figure: This pair represents a specific geometric shape and a general term for any shape or form. A triangle is a type of figure, so this pair is also consistent and not odd.

3. Kidney - Organ: This pair represents a specific organ found in the human body. The word "kidney" and "organ" are related in terms of category and classification, so this pair is consistent and not odd.

4. Fruit - Apple: This pair is the odd one out. While an apple is indeed a type of fruit, it is also a specific example of a fruit. The word "fruit" is a general term that encompasses various types of fruits. The relationship between "fruit" and "apple" is different from the relationships in the other word pairs. The other pairs follow a pattern where one word is a specific example or type within the broader category represented by the other word. However, in the case of "fruit" and "apple," both words represent different levels of specificity within the same category, making it the odd pair.

Hence, the correct answer is 4) Fruit - Apple.

Faces opposite to each other is shown below:

Hence, 'option 3' is the correct answer.

Equation I: 24 ÷ 8 × 2 + 7 - 6

After interchanging × and -, we get the equations:

→ 24 ÷ 8 - 2 + 7 × 6

→ 3 - 2 + 7 × 6 =?

→ 3 - 2 + 42 =?

→ 45 - 2 = 43.

Equation II. 8 × 6 - 9 ÷ 3 + 10

After interchanging × and -, we get the equations:

→ 8 - 6 × 9 ÷ 3 + 10

→ 8 - 6 × 3 + 10 =?

→ 8 - 18 + 10 =?

→ 18 - 18 = 0.

Hence, the correct answer is " 43 and 0 ".

Given:
