If the FROG is coded as 719168 then what should be the code for TRIP?

Question

If
397 is coded as 210191,
459 is coded as 360881 and
123 is coded as 030260

Then what is the code for 789?

Answer 1

21191017
Take each letter and assign it by its number A=1, B=2, C=3...
Add 1.

Answer 2

The number 719168 can be written as 7 19 16 8
the number 7 coincides to alphabetic order of letter F plus 1
the number 19 coincides to alphabetic order of letter R plus 1
the number 16 coincides to alphabetic order of letter O plus 1
the number 8 coincides to alphabetic order of letter G plus 1

Then word TRIP
Alphabetic order of letter T is 20
alphabetic order of letter R is 18
alphabetic order of letter I is 9
alphabetic order of letter P is 16

Then the code will be 21191017
