Step-by-step explanation:

Given : If 20 workers can complete a task in 45 days.

To find : How many more workers will be required to complete it in 30 days?

Solution :

Since there is an inverse relation between workers and days.

So, If 20 workers can complete a task in 45 days.

Let x be the workers required to complete task in 30 days.

According to method,

$20\times 45=x\times 30$

$900=x\times 30$

$x=\frac{900}{30}$

$x=30$

The number of days more required is 30-20=10.

So, 10 more workers will be required to complete it in 30 days.
