The weekly salary is = XY
If the new hourly rate is = X(1-10%)
Then, in order to keep the same weekly salary, the new working hours is = Y/(1-10%)
= 1/(1-0.1) = 1.111..
Therefore, in order to keep the same weekly salary, the worker should increase (100/9)% or 11.11% (2 d.p.) of working hours per week.Source(s): myself... 嚴禁抄襲
