Answer»

Worth of electronic goods=Rs.10000

Sales tax=4%

CP of electronic goods=10000x104/100=10000x1.04=Rs.10400

Worth of other material=Rs.15000

Sales tax=6%

CP of other material=15000x106/100=15000x1.06=Rs.15900

CP of whole equipment for manufacturing the gadget=10400+15900=Rs.26300

Profit%=15%

SP=CPx100+P%/100

=26300x100+15/100

=26300x115/100

=26300x1.15

=30245

SP of gadget=Rs.30245
