A, B and C work on a task

A, B and C work on a task. To complete the task alone, B takes twice the time that A would take to complete the task alone and 1/5rd the time that C would take to complete the task alone. If B actually worked for half the number of days that A worked and 3/2 times the number of days that C worked, what proportion of the total work was completed by B?
