Question

there has been increment in the wages of labourers in a factory in the ratio of 22:25 but there has also been a reduction in the number of labourers in the ratio of 15:11. find out in what ratio the total wage bill of the factory would be increased or decreased

Answer 1

%reduction is 6-5/6×100=16.67%
ration 5:6

Answer 2

let intial wage = 22x
after increment = 25x

intial labour = 15y
after decrement = 11y

intial total bill = 22*15xy = 330xy
final total bill = 25*11xy = 275xy

%decrease = (330xy-275xy)*100/330xy = 16.67%
