Total time = 8 hrs.
Total Articles = 100
Work done by A = 3.5 * 8 = 28.
Work must be done by B = 72 articles.
Required Time for B : 72 / 8 = 9 articles / hr.
B is the correct answer.

Speed of A = 3.5 per hour
In 8 hours = 3.5*8 = 28 articles
—> Remaining articles = 100 - 28 = 72 articles
—> Required speed of B = 72/8 = 9 articles per hour
IMO Option C
