Question

The mean wage of 100 workers working in a factory running two shifts of 70 and 30 workers respectively is Rs. 84. The mean wage of 70 workers working in the morning shift is Rs. 90. Find the mean wage of 30 workers working in the evening shift

Answer 1

Step-by-step explanation:

total workers = 100

morning workers = 70

mean wages per day of morning workers=90×70

therefore wages of morning workers = rs6300

No of night workers= 30

therefore wages of night workers = 30×90

that is =rs 2700

there fore mean wage = 2700/30 ×100
