Correct Answer: Havana : Cuba

Solution : Given:
Tokyo : Japan (Tokyo is the capital city of Japan.)

Let's check the given options –
First option: Havana : Cuba; Havana is the capital city of Cuba.
Second option: Thailand : Bangkok; Bangkok is the capital city of Thailand but the order is different.
Third option: Egypt : Cairo; Cairo is the capital city of Egypt but the order is different.
Fourth option: Italy : Rome; Rome is the capital city of Italy but the order is different.

So, only the first option follows the same pattern as followed by the given pair. Hence, the first option is correct.

Correct Answer: 3744 – 11322

Solution : The logic followed here is – First number × 3 = Second number

Let's check the options –
First option: 3744 – 11322→3744 × 3 = 11232 ≠ 11322
Second option: 1008 – 3024→1008 × 3 = 3024
Third option: 2278 – 6834→2278 × 3 = 6834
Fourth option: 3072 – 9216→3072 × 3 = 9216

So, the first option doesn't follow the logic. Hence, the first option is correct.

Correct Answer: Cattle : Herd

Solution : Given:
Soldiers : Army (This depicts the relation that a group of soldiers is known as an army).

Let's check the options –
First option: Singers : Gang; A group of singers is called a choir, not a gang.
Second option: Cattle : Herd; A group of cattle is called a herd.
Third option: Class : Pupils; A group of students is called pupils.
Fourth option: Team : Players; A group of players is called a team, but the order is incorrect.

So, only the second option follows the pattern as followed by the given pair. Hence, the second option is correct.

Correct Answer: Experiments

Solution : Given:
Mathematics : Logic :: Science : ?

Like, mathematics is a subject that needs logic for each question and theorem to be proved.
Similarly, science is a subject that needs experiments to be proved for any conclusion.

Hence, the first option is correct.

Correct Answer: Nephew

Solution : Given:
Sister: Brother :: Niece : ?

Like, sister is used for female and brother is used for male.
Similarly, the niece is female and the nephew is male.

Hence, the fourth option is correct.

Correct Answer: Shoot : Gun

Solution : Given:
View : Binocular (A binocular is an instrument used for viewing.)

Let's check the options –
First option: Spade : Dig; A spade is a tool used for digging. But, the order is not according to the question.
Second option: Pen : Write; A pen is a tool used for writing. But, the order is not according to the question.
Third option: Shoot : Gun; A gun is an instrument used for shooting. 
Fourth option: Feed : Spanner; A spanner is a tool used for tightening or loosening nuts and bolts.

So, only the third option follows the same pattern as followed by the given pair. Hence, the third option is correct. 

Correct Answer: 3333 – 1111

Solution : Let's check the options –
First option: 6666 – 3333; 6666 ÷ 2 = 3333
Second option: 8888 – 4444; 8888 ÷ 2 = 4444
Third option: 4444 – 2222; 4444 ÷ 2 = 2222
Fourth option: 3333 – 1111; 3333 ÷ 2 = 1666.5 ≠ 1111

So, only the fourth option is different from the other three options as 3333 is not completely divisible by 2. Hence, the fourth option is correct.

Correct Answer: 24 – 575

Solution : Let's check each option –
First option: (24 – 575); 24² + 1 = 576 + 1 = 577 ≠ 575
Second option: (14 – 197); 14² + 1 = 196 + 1 = 197
Third option: (12 – 145); 12² + 1 = 144 + 1 = 145
Fourth option: (18 – 325); 18² + 1 = 324 + 1 = 325

Hence, the first option is correct.

Correct Answer: Ore : Metal

Solution : Given:
Leather : Shoes (Leather is a common material used in the manufacturing of shoes, i.e., the first word is the raw material and the second word is the final product.)

First option: Linen : Flax; Linen is a fabric made from the fibers of the flax plant. (Here, the first word is the final product and the second word is the raw material.)
Second option: Cloth : Fibre; Cloth is made from various fibres. (Here, the first word is the final product and the second word is the raw material.)
Third option: Ore : Metal; Ore is a primary source from which metals are extracted. (Here, the first word is the raw material and the second word is the final product.)
Fourth option: Sack : Jute; Jute is a natural material used in the manufacturing of sacks. (Here, the first word is the final product and the second word is the raw material.)

So, here all the options follow the same logic of the final material and its raw product but the order of words does not match. Only the third option follows the same logic and the same order. Hence, the third option is correct.

Correct Answer: 358 – 726

Solution : Let's check each option –
First option: (168 – 336); 168 × 2 = 336
Second option: (512 –1024); 512 × 2 = 1024
Third option: (358 – 726); 358 × 2 = 716 ≠ 726
Fourth option: (624 – 1248); 624 × 2 = 1248

So, the third option is different from the other three options. Hence, the third option is correct.
