A piece of work takes 20 labourers to complete in 10 days. how many labourers will complete the same job in 25 days if they work at the same rate?​

Sagot :

Step-by-step explanation:

If 20 labourers=10 days

x labourers = 25 days

10x= 25×20

[tex] \frac{10x}{10} = \frac{25 \times 20}{10}[/tex]

Cancelling out by 10 on both sides

[tex]x = \frac{25 \times 2}{1} \\ x = 50 [/tex]

Therefore, it takes 50 labourers to complete the work at the same rate in 25 days.
