Question

A worker is engaged for 30 days on the condition that he will receive Rs150 for each day he works and will be fined Rs 20 for each day he is absent. If he receives Rs 3650 in all , for how many days did he remain absent ?

Answer 1

30*150 = 4500 ( amount which he was supposed to get for one month)
He received 3650
4500-3650= 850
he was absent for 5 days as 750 were not given to him (150*5) and 100 were fined for being absent for 5days (20*5)

Answer is 5 days!
