Sandra and Mayuri, working together, can complete a job in 60 days. However, Mayuri works alone and leaves after completing a third of the job and then Sandra takes over and completes the remaining work by herself. As a result the duo could complete the job in 150 days. How many days would Sandra alone have taken to do the job if Mayuri worked faster than her?
