1. Which letter replaces the "?": L : O R : I E : V M : ?
Solution : N, because if we assign the values as A=1, B=2.....Z=26, then each pair adds upto 27. example : L O 12+15 = 27.
2. Find odd one out :
a) BHHP b) DPHD c) DDHH d) PPBD
Solution : (c), if we assign the values as A=1, B=2.....Z=26, then options a, b, d have same product of alphabets equal to 2048. example : B H H P 2 8 8 16 2x8x8x16 = 2048.
3. Which letter replaces the "?": A, D, ?, P, Y.
Solution : I, because if we assign the values as A=1, B=2.....Z=26, all the entries are perfect square numbers.
4. Which letter replaces the "?": A, C, ?, J, O, U.
Solution : F, because if we assign the values as A=1, B=2.....Z=26, the difference between consecutive entries increases by 1.
5. Which letter replaces the "?": A, Z, ?, X, E, V, G, T.
Solution : C, because if we assign the values as A=1, B=2.....Z=26, the difference between alternate entries is 2.
6. Find odd one out :
a) CO b) ZN c) FR d) JS
Solution : (d), if we assign the values as A=1, B=2.....Z=26, options a, b, c contain pair having number difference 12. example : C O 3 15 difference = 15 - 3 = 12.
