Question

25 labourers make a 7.5km long road in one week .how many labourers will make a road of 10.2 km in 1 week

Answer 1

Step-by-step explanation:

34 labourers are required to make a road of 10.2 km in 1 week

Solution:

Given, 25 labourers make a 7.5 km long road in one week.  

We have to find how many labourers will make a road of 10.2 km in 1 week

Now, work done by one labourer  

work done by a group of laborers/ no. of laborers= 7.5/25 = 0.3

Now, number of labours required  

work to be done/ work that can be done by a single laborer = 10.2/0.3

Hence, 34 labourers are required to make a road of 10.2 km in 1 week
