Option 4 : 57

The positions of the letters according to the English alphabet series:

The pattern for this code is as follows;

__LOGIC__: Sum of positional value + (Number of Letters)1^{ or 2}

**If the number of letters is even then power is 1.**

**If the number of letters is odd then power is 2.**

In MAPED:

**Number of letter = 5 (Odd)**

MAPED = (13 + 1 + 16 + 5 + 4) + 5^{2}

= 39 + 25

= 64

And;

In RECK:

**Number of letter = 4 (Even)**

RECK = (18 + 5 + 3 + 11) + 4

= 37 + 4

= 41

Similarly;

In NOSE:

**Number of letter = 4 (Even)**

NOSE = (14 + 15 + 19 + 5) + 4

= 53 + 4

= 57

Hence,** "57"** is the correct answer.
