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: 51624 – 42615
Option 2: 51678 – 87615
Option 3: 42675 – 57624
Option 4: 12311 – 11231
Correct Answer: 12311 – 11231
Solution : Let's check the options – First option: 51624 – 42615; Reversing the digits of 51624 leads to 42615. Second option: 51678 – 87615; Reversing the digits of 51678 leads to 87615. Third option: 42675 – 57624; Reversing the digits of 42675 leads to 57624. Fourth option: 12311 – 11231; Reversing the digits of 12311 leads to 11321 ≠ 11231
So, only the fourth option is different from the other three options. Hence, the fourth option is different.
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. Mammal : Man :: Reptile : ?

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. Square : Four :: ? : ?
Option 1: Six : Hexagon
Option 2: Triangle : Five
Option 3: Rectangle : Four
Option 4: Five : Pentagon
Correct Answer: Rectangle : Four
Solution : Given: Square : Four (This depicts the name of the figure with the number of sides in the figure.)
Let's check the options – First Option: Six : Hexagon→Hexagon has six sides but the words are not in the correct order. Second Option: Triangle : Five→Triangle has three sides, not five. Third Option: Rectangle : Four→Rectangle has four sides. Fourth Option: Five : Pentagon→Pentagon has five sides but the words are not in the correct order.
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: 3241 – 5732
Option 2: 2354 – 4835
Option 3: 1326 – 3807
Option 4: 2345 – 4826
Correct Answer: 3241 – 5732
Solution : Let's check each option – First option: (3241 – 5732); 5732 – 3241 = 2491≠ 2481 Second option: (2354 – 4835); 4835 – 2354 = 2481 Third option: (1326 – 3807); 3807 – 1326 = 2481 Fourth option: (2345 – 4826); 4826 – 2345 = 2481
So, only the first option doesn't follow the same pattern as followed by the given set of numbers. Hence, the first option is correct.

Option 1: 15 – 56
Option 2: 13 – 48
Option 3: 11 – 39
Option 4: 17 – 64
Correct Answer: 11 – 39
Solution : Let's check each option – First option: 15 – 56; 15 × 4 = 60 and 60 – 4 = 56 Second option: 13 – 48; 13 × 4 = 52 and 52 – 4 = 48 Third option: 11 – 39; 11 × 4 = 44 and 44 – 4 = 40 ≠ 39 Fourth option: 17 – 64; 17 × 4 = 68 and 68 – 4 = 64
So, only the third option doesn't follow the same pattern as followed by the given set of numbers. Hence, the third option is correct.
Question : Directions: BK19 is related to DM21 in a certain way. In the same way, RC11 is related to TE13. To which of the following is MJ17 related following the same logic?
Option 1: PL19
Option 2: NK20
Option 3: OL19
Option 4: OM21
Correct Answer: OL19
Solution : Given: BK19 ⇒ DM21, RC11⇒ TE13.
Add 2 to the positional values of each letter and number of the given term to obtain the code — BK19→B + 2 = D; K + 2 = M; 19 + 2 = 21 Thus, BK19 is coded as DM21. RC11→R + 2 = T; C + 2 = E; 11 + 2 =13 Similarly, for MJ17→M + 2 = O; J + 2 = L; 17 + 2 = 19
So, MJ17 is coded as OL19. Hence, the third option is correct.

Option 2: 9 – 84
Option 3: 13 – 172
Option 4: 11 – 124
Correct Answer: 15 – 220
Solution : Let's check the options – First option: 15 – 220; (15)2 + 3 = 225 + 3 = 228 ≠ 220 Second option: 9 – 84; (9)2 + 3 = 81 + 3 = 84 Third option: 13 – 172; (13)2 + 3 = 169 + 3 = 172 Fourth option: 11 – 124; (11)2 + 3 = 121 + 3 = 124
So, only the first option is different from the other three options. Hence, the first option is correct.
