Question
45 people can repair a road in 10 days working 6 hours a
day. In how many days can 30 people working 6 hours a day complete the same work?Solution

Then, total work = 45x × 10 × 6 = 2700x
So, number of days taken by 30 people working 6 hours a day to complete the same work
= 2700x ÷ (30x × 6) = 15 days
