Correct Answer: 20 days
Solution : Given: X boys can do the work in 80 days. If 2X boys are doing half the work, they would take half the time of half the original time, which is a quarter of the original time. $\therefore$ 2X boys will do half of the work = $\frac{1}{4}×80$ = 20 days Hence, the correct answer is 20 days.
