First of all you get 15 toffee in Rs.15, then you get 15/3 = 5 toffees from 15 wrappers.

Now you have 5 wrappers => 1 toffee + 2 wrappers => 3 wrappers => 1 toffee
Total number of toffees you get => 15 + 5 + 1 + 1 => 22 toffee’s.

Here we need to count the number of individual digits, how many 1’s, how many 2’s etc.
for example
1 => one 1 => 11
11 => two 1 => 21
21 => one 2 one 1 => 1211
Thus to get 5th number in the series
111221 => three 1 two 2 one 1 => 312211
And to get the sixth number in the series
312211 => one 3 one 1 two 2 two 1=> 13112221
