A group of workers includes some males and some females. A worker, whether male or female, can fill a canal 10 times as fast as she/he can dig it. It is known that 1 male and 7 females dug a canal in 6 days while 1 male and 3 females filled it in just one day. How many days will one male and one female take to dig the same canal If each worker (within their gender) has the same efficiency whether digging or filling the canal?
