Solution:Here we can see in case of LITTLE number of alphabets = 6, now its code
= 24 ⇒ 2 + 4 = 6
In case of PARIS, number of alphabets = 5, now its code = 23 ⇒ 2 + 3 = 5
In case of both BOX & PIN, number of alphabets = 3, now its code = 12 ⇒ 1 + 2 = 3
So, in case of DONE, number of alphabets = 4, now its code will be 4
= 2 + 2 = 22
