x and y together can completes a work in 12 days and y complete the same work in 24 days . then the number of days x required to complete the work will be ?
x and y complete in one day = 1 / 12 part , y completes in one day = 1 / 24 parts . therefore x alone can do in one day = 1 / 24 part . therefore the work can be finished by x = 24 days . ans : c
inverse(subtract(inverse(12), inverse(24)))
