Problem

During an automated daily task a computer spends 20% of the time importing the raw data from thousands of text files, 70% of the time processing it, and 10% of the time exporting the results to spreadsheet files and archiving the data.

To help speed-up the task a new chip is purchased that will double the speed of the processing task and the newly purchased hard drives allow both import and export times to be reduced by 30%.

How much time will be saved overall and what percentage of the time will be spent doing each of importing, processing, and exporting the data?
