The  logic followed here is :

THE PLACE VALUE OF G IS  7 , 7 + 7 = 14 WHICH IS N

THE PLACE VALUE OF H IS  8 , 8 + 8 = 16 WHICH IS P

G → (+7) → N

 P → (-8) → H

SIMILARLY

THE PLACE VALUE OF E IS  5 , 5 +5 = 10 WHICH IS J

THE PLACE VALUE OF J IS  10 , 10 + 10 = 20 WHICH IS T

 E → (+5) → J

 T → (-10) → J
