A hotel has 120 identical bedrooms. It uses labour efficiency percentages to compare the performance of four groups of workers (A, B, C and D) employed to clean the bedrooms. The standard time to clean a bedroom is 40 minutes.
The following data for last week are available:
Group A actual hrs worked- 128 actual #of bedrooms cleaned – 198
B actual hrs worked- 140 actual #of bedroom cleaned- 207
C actual hrs worked- 124 actual #of bedroom cleaned- 186
D actual hrs worked- 108 actual #of bedroom cleaned- 165it says that the correct answer is group A for most efficient, but they didn’t show the solution..
the formula for labour eff. ratio is standard hrs for actual output/actual hrs worked*100
if im gonna get for group A is this solution correct .. 0.66*198/128*100?
and 0.66 came from 40minutes/60minutesFor A, the standard time for cleaning = 198 rooms x 40/60 hours = 132 hours.
Therefore efficiency ratio = 132/128 = 103%
