Thank you very much
May I know why add 4 to 225? Thank you.
@Cindy...
Question asked for greatest possible number of letters.
1 group ABACA has 3 A.
45 groups have 45×3=135 A.
So, another 2 A can take from ABAC = 4 Letters from here.
45 group with ABACA =45×5=225
225 + 4 = 229.
Hope this clarify your doubts.
