X can do the work in 20 days, so X's work rate is 1/20 of the work per day.

Y can do the work in 12 days, so Y's work rate is 1/12 of the work per day.

X works alone for 4 days, completing 4/20 = 1/5 of the work.

Y joins X, and together they complete the remaining 4/5 of the work.

Their combined work rate is (1/20 + 1/12) = 8/60 = 2/15 of the work per day.

Since they complete 4/5 of the work together, it takes them (4/5) / (2/15) = 6 days to complete the remaining work.

Adding the 4 days X worked alone, the total duration is 4 + 6 = 10 days.

So, the correct answer is: 10 days.
