Answer:

The correct answer to this question is option (1).

Explanation:

Let x1 = Is number of pages that printer A can print  in page/minute.  

thus x1 + 5 = Is number of page that printer B can print in page/minute.  

As printer A finishes his work in 60 min. So the task has 60x1 pages. As printers A and B both finish that task in 24 minutes. So the equation can be given as:  

60x1 = 24x1 + 24(x1 + 5)  

 

60x1 = 24x1 + 24x1 + 120  

 

60x1=48x1 + 120

 

60x1-48x1=120

 

12x1=120  

 

x1=120/12

 

x1=10

put the value of x1 in to (60x1). Therefore, the task has 60(10) = 600 pages. the task contains 600 pages.  

So the answer to this question is option (1).
