*********************************************

THE LOGIC FOLLOWED HERE IS :

REVERSE THE WORD THEN ADD OF NUMBER ACCORDINGLY

LABOUR = ROUBAL

R → (+6) → X

O → (+5) → Z

U → (+4) → S

B → (+3) → E

A → (+2) → C

L → (+1) → M

AND

GAINED = DENIAG

D → (+6) → J

E → (+5) → J

N → (+4) → R

I → (+3) → L

A → (+2) → C

G → (+1) → H

SIMILARLY

EARNED = DENRAE

D → (+6) → J

E → (+5) → J

N → (+4) → R

R → (+3) → U

A → (+2) → C

E → (+1) → F
