Step-by-step explanation:

It Takes 6 Hours Per Day For 20 Workers

To Prepare 35 Articles.How Many Hours

Per Day Are Required By 15 Workers To

Do The Same Work

Answer 2

Let the extra hours be (x).

So, According to the first statement.

35 = 6/20 = 3/10.

And, According to the second statement.

35 = 6+x/15.

Therefore, 3/10 = 6+x/15.
=> 60 + 10x = 45.
=> 10x = -15.
=> x = -3/2.
As we now that time is always positive.
Therefore, X => 1.5 hours.
