Question

If FEATURES is written as GCDPZLLK in a code, what will be the fourth letter from the left, if ADVANTAGE is written in that code?

Answer 1

F E A T U R E S - G C D P Z L L K
G is one alphabet after F
C is two alphabets before E
D is three alphabets after A
P is four alphabets before T
Z is five alphabets after U
L is six alphabets before R
L is seven alphabets after E
K is eight alphabets before S

So by that we can say 
A - one alphabet after A is B
D- two alphabets before D is B
V- three alphabets after V is Y
A- four alphabets before A is W
N not necessary to calculate 
A not necessary to calculate 
G not necessary to calculate 
E  not necessary to calculate 

so the fourth letter from the left, if ADVANTAGE is written in that code  is 'W'
