ANSWER IS 

                 OPTION D  .  15A+10B


value for total  apples purchased  =  value for one apple * number of apples

                                               =  15 * number of apples

                                              = 15  A

value for total banans purchased  =  value for one banana* number of bananas

                                                    =  10 * number of bananas

                                                     = 10 B


SO TOTAL VALUE =  value for total  apples purchased  + value for total banans purchased 

                                =   15  A +  10 B .....................answer 

                                = OPTION D.
