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: 13 – 2199
Option 2: 14 – 2745
Option 3: 12 – 1729
Option 4: 17 – 4914
Correct Answer: 13 – 2199
Solution : Let's check each option – First option: 13 – 2199; 133 + 1 = 2197 + 1 = 2198 ≠ 2199 Second option: 14 – 2745; 143 + 1 = 2744 + 1 = 2745 Third option: 12 – 1729; 123 + 1 = 1728 + 1 = 1729 Fourth option: 17 – 4914; 173 + 1 = 4913 + 1 = 4914
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.

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: 21 – 1020
Option 2: 17 – 1006
Option 3: 11 – 1010
Option 4: 23 – 1022
Correct Answer: 17 – 1006
Solution : Let's check each option – First option: 21 – 1020; 1020 – 21 = 999 Second option: 17 – 1006; 1006 – 17 = 989 ≠ 999 Third option: 11 – 1010; 1010 – 11 = 999 Fourth option: 23 – 1022; 1022 – 23 = 999

Question : Directions: GB13 is related to HD17 in a certain way. In the same way, DK18 is related to EM22. To which of the following is RE16 related following the same logic?
Option 1: TF20
Option 2: TG19
Option 3: SG20
Option 4: SF18
Correct Answer: SG20
Solution : Given: GB13 is related to HD17 and DK18 is related to EM22.
Add 1 and 2 to the place value of the first and second letters respectively, and 4 to the number of GB13 and DK18 to obtain the required codes – GB13→G + 1 = H; B + 2 = D; 13 + 4 = 17 Thus, GB13 is related to HD17. DK18→D + 1 = E; K + 2 = M; 18 + 4 = 22 Thus, DK18 is related to EM22. Similarly, follow the same pattern for RE16 – R + 1 = S; E + 2 = G; 16 + 4 = 20
Thus, RE16 is related to SG20. Hence, the third option is correct.
