What percent of the students have either black or Red Pens?

In a group of 100 satudents, 48 have black pens, 32 have Blue Pens and 20 have red pens.

This is a simple ratio problem.

48 + 20
———–
100

= 68 / 100 = 68%

You could do it another way:
48 / 100 = 48%
20 / 100 = 20%
48% + 20% = 68%

Good luck in your studies,
