Question

A labourer is engaged for 20 days on the condition that he will revive Rs. 280 for each day he works and will be fined Rs. 60 for each day he is absent. If he receives Rs. 2540 in all, for how many days did he remain absent?

Solution

No of days he worked = x
No. of days he didn't work = 20 - x
According to question,
Rs.280(x) - Rs.60(20 - x) = Rs 2540
x = 11
No of days he worked = 11
No of days he was absent = 20-11=9
