Expert Answer
6 workers build a road of length 120 m in 6 days.
length of road build by 6 workers in one day = 120/6 = 20 m
length of road build by 1 worker in one day = 20/6 m
length of road build by 15 workers in one day = (20/6)×15 = 50 m
no. of days required for 15 workers to build 150 m road = 150/50 = 3 days.
