A group of workers had agreed on a very strange payment schedule. Each of
them would get $100 for every day that they had worked, but for every day they
did not work will have to return $25. After 30 days they realised they did not
earn any money. How many days the workers did not work?
Choices
A) 15  B) 24  C) 30  D) 20  E) 10

Rationale: the workers earn 4 times more than they have to return per day for not working . so the number of days they did not work is 4 times the number of days they worked . that means 24 days of not working in 30 days . correct answer b
Answer: B
