Question

a employer finds that if he increases the weekly wages of each worker by five and employer five worker less he increases his weekly wages bill from 3150 to 3250 find weekly wages of each worker

Answer 1

Let the number of workers=x

Let the weekly wage of the worker=yRs

Given
xy=3150........i)

(x-5)(y+5)=3250

xy-5y+5x-25=3250

or
x-y=25.....ii)

Solving i) and ii)
y(y+5)=3150

y²+25y-3150=0
y=45 or
y=-70(not possible)

Hence the weekly wage of the workers is 45 Rs.
