Solution Algorithm 1:

Defining Problem:

Input

Processing

Output

Recording                 transaction                                                         Retail_cost                                  Transaction_code                               Employee_No.

Reading transaction                                           Calculating                        commission                       Printing details of transaction

Retail cost                         Commission                      Employee No.

Pseudo code algorithm:

If the case of solution is not A, B or C then a message is printed and commission set as 0.

Process transaction record

Read retail_cost, transaction_code and employee_no.

CASE Transaction_Code

A: Commission = retail_cost x 0.06

B: Commission = retail_cost x 0.08

C: Commission = retail_cost x 0.1

Other: Displaying ‘Invalid transaction’, Transaction_code commission  = 0

END CASE

Print ‘Retail Price’, retail_cost, ‘Commission’, commission, ‘Employee No.’, Employee_No.

END
