Some letters are given below in the first line and numbers are given below them in the second line.Numbers are code for the alphabets and vice-versa.Choose the correct number code for given set of alphabets.

C   W   E   A   Z   X   J   Y   K   L
3   9   5   7   4   8   1   0   2   6

Find the code for J W X C L Z

From given question it is clear that the alphabet at odd position from beginning are intact in the code and the alphabet at even positions are replaced by the next alphabets in alphabetical order.
L + 0 = L
O + 1 = P
F + 0 = F
T + 1 = U
Y + 0 = Y

So the code for DWARF is DXASF

Subtract one from number of alphabets in the given word
Total number of alphabets in GOVERNMENT = 10.
So the code for GOVERNMENT is 10-1 = 9

From given code it is clear that the alphabets of the word are written in reverse order.

So the code for LADYFINGER is REGNIFYDAL

If a alphabate is at 'nth' position in their alphabetical order from the beginning then code is the alphabet at 'nth' position from the end.

So the code for REQUIRED is IVJFRIVW.

From question
PARK ? 5394 ....(i)
SHIRT ? 17698 ...(ii)
PANDIT ? 532068 ...(iii)

from (i), (ii) and (iii)
N ? 2
I ? 6
S ? 1
H ? 7
A ? 3
R ? 9

So code for NISHAR is 261739

5 - 4 = 1, 4 - 3 = 1 ? 1 + 1 = 2
6 - 0 = 6, 5 - 1 = 4, ? 6 + 4 = 10
6 - 2 = 4, 7 - 2 = 5 ? 4 + 5 = 9

QFODJM

15/20 x 5/4 x 2/3 x 8/5 = 1

The given logic is as follows-
word : F A T H E R
Logic : +2 +2 +2 +2 +2 +2
code : H C V J G T
Similarly, the code for 'SHIP' is 'UJKR' .
