It should be noted that the number of days that will be taken to complete the sales target will be 27 days.
<h3>How to compute the sales target</h3>
From the complete information, the following can be deduced:
a + b = 1/30
b + c = 1/40
a + c = 1/60
Using the rules of algebra, b = 5/240, a = 3/240.
a + c = 1/60
3/240 + c = 1/60
c = 1/60 - 3/240
c = 1/240
Therefore, the 3 can do 9/240 in a day. The number of days required will be:
= 240/9 = 27 days
