Just see if you can solve the question.
Q. If John and Felix work for 5 hours daily, then finish a work in 2 days. If Felix and Matt work for 5 hours every day the same work is completed in 4 days. If the same work is done by John and Matt they need to work for 6 hours a day to complete a work in 2 days. If each of them works 5 hours daily then in how many days each of them will finish the same work?
