Question

A labour is engaged for 20 days on the condition , that he will receive Rs. 60 for each day he works and he will be fined Rs.5 for each day he is absent. If he receive Rs.745 in all, for how many days he remained absent? what values are depicted by the employer

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 = 7 days absent
:
:
Check this, he worked 13 days so we have:
13(60) - 7(5) = 
780 - 35 = 745;
