Question

there has been increment in the wages of labourer 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 is the total wages bill of the factory would be increased or decreased​

Answer 1

Step-by-step explanation:

Let, before increment, the wage of each labourer be w and the number of labourers be n.

Then , the wage bill , before increment=w×n or w•n.

After increment ,

wage of each labourer, w’= 25w/22 and

number of labourers , n' = 11/15 .

Thus , the wage bill after increment = w'×n’

=25w/22×11n/15=5/6 w•n =5/6 of the pre - increment wage bill.

Hence, the post-increment wage bill is reduced by 1/6 of the pre-increment wage bill.
