DS 1 Adam, Ben, and Clara are hired to weed a garden at a community center. If Adam and Ben, working simultaneously and independently at their respective constant rates, can weed the garden in 6 hours, how long would Adam and Clara, working simultaneously and independently at their respective constant rates, take to weed the garden?
(1) Adam, Ben, and Clara, working simultaneously and independently at their respective constant rates, can weed the garden in 4 hours.
(2) Ben, working alone at his constant rate, would take 50% more time to weed the garden than Adam, working alone at her constant rate, would take.

DS 2 Starting at the beginning of 2007, a research lab’s data archive increased by 20% each year for a whole number of years. If no data was deleted during this period, how many gigabytes of data were in the archive at the end of the period?
(1) By the end of the period, the amount of data in the archive had increased by 44%.
(2) If 360 gigabytes of data had been deleted at the beginning of the final year of the period, the amount of data in the archive at the end of the period would have been 12% less than its actual amount at the end of the period.
