**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.
