Answer:
10 Days and 22 % of 11 th day
Step-by-step explanation:
A per day Completion percentage = 1/30=3.33 %
B per day Completion percentage = 1/20=5.00 %
C per day Completion percentage = 1/15=6.67 %
Day 1 = A+B = 3.33% +5.00 % = 8.33 %
Day 2 = B+C= 5.00 % + 6.67 % = 11.67 % Cumulative 20 %
Day 3 = C+A= 6.67 % + 3.33 % = 10.00 % Cumulative 30 %
Day 4 = A+B = 3.33% +5.00 % = 8.33 % Cumulative 38.33 %
Day 5 = B+C= 5.00 % + 6.67 % = 11.67 % Cumulative 50 %
Day 6 = C+A= 6.67 % + 3.33 % = 10.00 % Cumulative 60 %
Day 7 = A+B = 3.33% +5.00 % = 8.33 % Cumulative 68.33 %
Day 8 = B+C= 5.00 % + 6.67 % = 11.67 % Cumulative 80 %
Day 9 = C+A= 6.67 % + 3.33 % = 10.00 % Cumulative 90 %
Day 10 = A+B = 3.33% +5.00 % = 8.33 % Cumulative 98.33 %
11.67 % - 1 Day
then 2.67 % = ? =
=(2.67*1)/11.67= 22 % of 11 Day
Day 11 = B+C= 2.67 % Cumulative 100 %
