This takes up a total of 89 x 2 = 178 digits.
After this, number of digits remaining
= 337 - 178
= 159
The remaining participants has 3 digits in their tags each, so the number of participants having 3 digits in their tags
= 159 / 3
= 53
So, the total number of participants
= 89 + 53
= 142

337-11= 326 this is the amount from 12 - 337 and since 11 is used it will be :
326+1= 327
