Answer 2

The owner save (3-2)=1 day because of this decision.

Step-by-step explanation:

Since we have given that

Number of workers = 12

Number of days = 9

If after 6 days, there is 4 more workers ,

So, it becomes,

Number of workers × (Difference of days ) = number of workers × number of days

$12\times (9-6)=16\times d\\\\12\times 3=16d\\\\\dfrac{36}{16}=d\\\\d=2.25\\\\d=2\ days$

Hence, the owner save (3-2)=1 day because of this decision.
