1.Kamau completed a job in 45 hours for which 60 hours were allowed. His wage rate per hour is shs 16.
Calculate kamau’s total wage according to :-
a) Halsey scheme (2 marks)
b) Halsey-Weir scheme ( 2 marks)
c) Rowan scheme ( 2 marks)
Solution:
a.). Halsey scheme:
Formula = Hours worked "\\times" Rate per hour + (50"\\% \\times" time saved "\\times" rate per hour)
= 45 "\\times" 16 + ((50"\\% \\times" (60 – 45) "\\times"16) = 720 + 120 = shs.840
b.). Halsey-Weir scheme:
Formula = Formula = Hours worked "\\times" Rate per hour + ("33\\frac{1}{3}""\\% \\times" time saved "\\times" rate per hour)
= 45 "\\times"16 + (("33\\frac{1}{3}""\\% \\times" (60 – 45) "\\times"16) = 720 + 79.99 = shs.799.99
c.). Rowan scheme:
Formula = Hours worked "\\times" Rate per hour + ("\\frac{Time\\; taken}{Time \\;allowed}" "\\times" time saved "\\times" rate per hrs)
= 45 "\\times"16 + ("\\frac{45}{60}" "\\times"15 "\\times"16) = 720 + 180 = shs.900
