HOPE IT HELPS.......
Step-by-step explanation:
Mean wage of 150 workers=Rs.114.00
∴Total wage of 150 workers=150×114.00=Rs.17100
No of person work in first shift=60
Mean wages of 60 workers=Rs.121.50
∴ Total wage of 60 workers=60×121.50=Rs.7290
No of person work in first shift=40
Mean wages of 60 workers=Rs.107.75
∴ Total wage of 60 workers=40×107.75=Rs.4310
Total wages of the person who work in first and second shift=7290+4310=Rs.11600
∴Total wages of the person who work in third shift=17100−11600=Rs.5500
Mean wages of those who work in third shift=
50
5500
=Rs.110
Given:
Mean wage of 100 workers =Rs.38
Total wage of workers = 100 × 38 = 3800
No of person work in morning shift=60
Mean wages of 60 workers = Rs.40
∴ Total wage of 60 workers= 40 × 60 = Rs.2400
No of person work in evening shift= 40
Total wage of 40 workers = 3800 - 2400
=1400
1400/40=35
Hence the mean wage of 40 workers working in the evening shift Rs.35
