Question

A man was engaged as typist for the month of february in 2016 .He was paid ₹500 per day but ₹100per were deduct for the days he remained absent . He recived ₹ 9100 as salary for the month . For how many days he work?

Answer 1

working days x
absent days 29-x
working salary = 500× x
absent salary = 100× (29-x)
Total salary = working days - absent days
= 500x -100 (29-x) = 9100

500x - 2900 + 100x = 9100

600x = 9100+2900

600x = 12000

x = 20

so working days = 20 days
absent days 29-20= 9days

Answer 2

There are 29 days in February 2016
Let’s say he attends x days
Therefore
500x -(29-x)*100=9100
Therefore,
500x-2900-(-100x)=9100
600x=12000
X=20 days
