Logic
Question : Directions: In the following question, four number pairs are given. In each pair, the number on the left side of (–) is related to the number on the right side of (–) with some Logic/Rule /Relation. Three pairs are similar based on the same Logic/Rule/Relation. Select the odd one out from the given alternatives. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 – operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Option 1: 14 – 2844
Option 2: 12 – 1728
Option 3: 20 – 8000
Option 4: 10 – 1000
Correct Answer: 14 – 2844
Solution : Let's check each option – First option: 14 – 2844; 143 = 2744 ≠ 2844 Second option: 12 – 1728; 123 = 1728 Third option: 20 – 8000; 203 = 8000 Fourth option: 10 – 1000; 103 = 1000
So, only the first option is different from the others. Hence, the first option is correct.
Question : Directions: Words given on the left side of (::) are related to each other by some Logic/Rule/Relation. Select the missing word/word pair on the right side of (::) from the given alternatives based on the same Logic/Rule/Relation. Car : Steering :: Fan : ?
Option 1: Three
Option 2: Electricity
Option 3: Tyre
Option 4: Blade
Correct Answer: Blade
Solution : Given: Car : Steering :: Fan : ?
Like, a Car is controlled or operated by using its steering wheel. Similarly, for Fan, its operation is facilitated by its blades.
Hence, the fourth option is correct.
Question : Directions: In the following question, four number pairs are given. In each pair, the number on the left side of (–) is related to the number on the right side of (–) with some Logic/Rule/Relation. Three pairs are similar based on the same Logic/Rule/Relation. Select the odd one out from the given alternatives. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 – operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Option 1: 11 – 23
Option 2: 9 – 16
Option 3: 25 – 51
Option 4: 13 – 27
Correct Answer: 9 – 16
Solution : Let's check each option – First option: 11 – 23; 11 × 2 + 1 = 23 Second option: 9 – 16; 9 × 2 + 1 = 19 ≠ 16 Third option: 25 – 51; 25 × 2 + 1 = 51 Fourth option: 13 – 27; 13 × 2 + 1 = 27
So, only the second option doesn't follow the same pattern as followed by the given set of numbers. Hence, the second option is correct.
Question : Directions: Words given on the left side of (::) are related to each other by some Logic/Rule/Relation. Select the missing word/word pair on the right side of (::) from the given alternatives based on the same Logic/Rule/Relation. Ottawa : Canada :: ?
Option 1: Nairobi : Kenya
Option 2: Russia : Moscow
Option 3: Greece : Athens
Option 4: Spain : Madrid
Correct Answer: Nairobi : Kenya
Solution : Given: Ottawa : Canada :: ? (Ottawa is the capital city of Canada.)
Let's check the given options – First option: Nairobi : Kenya; Nairobi is the capital city of Kenya. Second option: Russia : Moscow; Moscow is the capital city of Russia, but the words are written in the reverse order. Third option: Greece : Athens; Athens is the capital city of Greece, but the words are written in the reverse order. Fourth option: Spain : Madrid; Madrid is the capital city of Spain, but the words are written in the reverse order.
So, only the first option follows the same pattern and order as followed by the given pair of words. Hence, the first option is correct.
Question : Directions: Words given on the left side of (::) are related to each other by some Logic/Rule/Relation. Select the missing word/word pair on the right side of (::) from the given alternatives based on the same Logic/Rule/Relation. Caterpillar : Butterfly :: ? : ?
Option 1: Tadpole : Cat
Option 2: Hen : Chick
Option 3: Lamb : Sheep
Option 4: Deer : Fawn
Correct Answer: Lamb : Sheep
Solution : Given: Caterpillar : Butterfly (It is a relation between an animal's young form and mature form. A caterpillar is in the larval (immature) stage, and a butterfly is in the adult stage of the same organism.)
First option: Tadpole : Cat; A tadpole is the larval stage of a frog, not a cat. Second option: Hen : Chick; A chick is the young stage or offspring of a hen but the order is different. Third option: Lamb : Sheep; A lamb is a young form of sheep. Fourth option: Deer : Fawn; A fawn is the young stage or offspring of a deer but the order is different.
So, only the third option follows the same pattern as followed by the given pair. Hence, the third option is correct.
Question : Directions: In the following question, four number pairs are given. In each pair, the number on the left side of (–) is related to the number on the right side of (–) with some Logic/Rule/Relation. Three pairs are similar based on the same Logic/Rule/Relation. Select the odd one out from the given alternatives. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Option 1: 1286 – 2578
Option 2: 3294 – 6589
Option 3: 1324 – 2649
Option 4: 3184 – 6369
Correct Answer: 1286 – 2578
Solution : Let's check the options – First option: 1286 – 2578; (1286 × 2) + 1 = 2572 + 1 = 2573 ≠ 2578 Second option: 3294 – 6589; (3294 × 2) + 1 = 6588 + 1 = 6589 Third option: 1324 – 2649; (1324 × 2) + 1 = 2648 + 1 = 2649 Fourth option: 3184 – 6369; (3184 × 2) + 1 = 6368 + 1 = 6369
So, only the first option is different from the other three options. Hence, the first option is correct.

Option 1: 6 – 60
Option 2: 2 – 18
Option 3: 4 – 40
Option 4: 8 – 80
Correct Answer: 2 – 18
Solution : Let's check the options – First option: 6 – 60→6 × 10 = 60 Second option: 2 – 18→2 × 10 = 20 ≠ 18 Third option: 4 – 40→4 × 10 = 40 Fourth option: 8 – 80→8 × 10 = 80
So, only the second option differs from the other three options as the product of the first number and ten is 20 instead of 18. Hence, the second option is correct.
