Answer: 120 days
Step-by-step explanation:
A can complete it in 16 days.
=100/16 =6.25%/day.
B has ten days to do it.
10% every day is equal to 100/10.
So they would each contribute 16.25 percent per day as a group.
then for six days,
16.25*6 =97.50percent
97.50% of the work has been finished, in other words.
The amount of work left is now 100-97.5 = 2.5.
C finishes up the remaining job in 3 days
3.5% in 3 days, to be exact.
Consequently, he will finish his entire project in 120 days.
[2.5 * 40 = 100 percent; 40 * 3 = 120 days]
