Total price after 6 years in Account II is :

Total balance, 
Hence, this is the required solution.
The number of applicants that were not accepted are calculated to be 1260.
The number of applicants that were not accepted can be determined as follows;
Since 2 out of every 9 applicants are accepted; therefore the total number of applicants out of which 360 applicants were accepted can be calculated as follows;
360 × 9 / 2 = 3240 / 2 = 1620
Therefore the total number of applicants is calculated to be 1620, out of these 1620 applicants, 360 were accepted therefore the number of applicants that were not accepted can be determined by subtraction.
The number of applicants that were not accepted can be determined by subtracting the accepted applicants from the total number of applicants as follows;
Applicants not accepted = 1620 - 360
Applicants not accepted = 1260
Therefore 1260 applicants were not accepted by the program.
