GMAT Practice Question Set #24 (Question 70-72)

Problem Solving Question #72: Sequencing the Human Genome (num days)  
Time 0 0 : 0 0 : 0 0

Recently, scientists were able to sequence an individual's humane genome in just 4 weeks using a
super fast modern computer. A computer manufactured just 2 years earlier would have taken 24
weeks to do the same amount of work.

For more targeted treatment of his cancer, Steve needs his human genome to be sequenced as
soon as possible and scientists plan to use both the super fast modern computer and the 2 year-
old computer to get the job done. Assuming both computers can tackle discrete components of
the genome sequencing process, how many days should doctors expect to have the results of
Steve's human genome sequencing project?
