Percentages: Question 8 - using minimum wage to calculate increase in wage bill


The union members of the staff of a construction company are negotiating a pay rise of 25% to maintain a minimum wage level in the industry.
The management of the company offers to grant the increment but to reduce workforce by 12% to maintain the current production level. If the union accepts this offer, what is the company’s percentage increase in wages?
Increase in wages = 25%
New wage expenditure will be
(100+25)% = 125%
Decrease in staff number = 12%
New staff number will be (100-12)% = 88%
wages expenditure = no of staff * wage rate.
Wages expenditure = 125% x 88%  =1.1
This means that wages expenditure will only increase by  0.1 x 100% = 10%.
