Data Interpretation| Q. | 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? |

Answer:D
Explanation: Let's calculate how much time it takes to repair the road if just 1 person were working on it. 5 hours a day for 12 days makes it 60 hours per person. 39 people working 60 hours each makes it 39*60=2340 hours in total. Now we have 30 people working 6 hours a day That means 30*6=180 hours are spent each day. We need a total of 2340 hours. With 180 hours every day, that's going to take 2340/180 = 13 days to complete... Or you could just do it in one step... :- 39*12*5 = 30*X*6 2340 = 180X X = 2340/180 X = 13. |

Answer:B
Explanation: Let be the original number of men Then 1 work done = x - 60 Then, 60x = (x + 8) 50 60x = 50x + 400 10 x = 400 x = 40. |
