1. Answer:

   No of clips in the box = 140

   Step-by-step explanation:

   no of red clips = 2x

   no of blue clips = 5x

   no of black clips = 7x

   The difference between the number of black and red paper clips is 20,

   7x-5x = 20

   2x = 20

   x = 10

   no of clips in the box,

   2x+5x+7x = 20+50+70 = 140
