Answer:
So, in 4 hours , 3 operators makes 6 articles.
Explanation:
In 5 hours 4 operators make 10 articles, how many articles will 3 operators make in 4 hours?
In 1 hour 4 operator makes 10/5 = 2 articles
In 1 hour , 1 operator makes = 2/4 = 0.5 article

In 4 hours, 3 operation makes = 1.5 x 4 = 6 articles
