If the bank wishes to shift an additional 30% of call center queries to IVR system, what would be the potential cost savings for the same number of queries?

A bank has observed that 60% of its customer queries are handled by its call center while 40% are handled through IVR system. If the average cost per call center query is Tk. 200 and the average cost per IVR interaction is Tk. 50, calculate the total cost for handling 12,000 customer queries?
