Quantitative Aptitude (Pb Patwari) Time and work

39 persons can repair a road in 12 days, working 5 hours a day. In how many days will 30 persons, working 6 hours a day, complete the work?

cause we have (39 * 5 = 195) vs (30 * 6 = 180) work hour per day.
195/180 = 13/12
so we need 12*13/12 = 13

Hence, option 2 is the correct answer.
