Solution

The correct option is C Team A is more efficient as average work done by a person is 6.4 units/day
Average work done in a day by a person in team A = $\frac{5 + 7 + 8 + 6 + 6}{5} = \frac{32}{5} = 6.4 u n i t s / d a y$
Average work done in a day by a person in team B = $\frac{5 + 7 + 6 + 5 + 5 + 8}{6} = \frac{36}{6} = 6 u n i t s / d a y$

Team A is more efficient.
