Question

A labour is engaged on work for 20 days on the condition that he will receive 60 rupees for each Day he works. And he will be fined 5 rupees for each Day he is absent . If he receives 740 rupees in all for how many days he remained absent?

Answer 1

Let a = number of days absent

then

(20-a) = number of days worked

:

Pay amt - fine amt = 745

 

60(20-a) - 5a = 745

1200 - 60a - 5a = 745

-65a = 745 - 1200

-65a = -455

a = %28-455%29%2F%28-65%29

a = 7 days absent

Check this, he worked 13 days so we have:

13(60) - 7(5) =

780 - 35 = 745; confirms our solution
