Before 'A' joined the team, 'S' and 'V' were alternating days to complete a project. In the final four days, 'A', 'S', and 'V' all worked together to finish the job. 'V' is 50% more efficient than 'S' and 20% more efficient than 'A'. If 'A' can complete the work by himself in 24 days and 'S' and 'V' worked for an equal number of days, calculate the total number of days it took to complete the work.
