Answer:
80 books
240 magazines
Step-by-step explanation:
let number of books = y
number of magazines = 3y
According to question
y + 3y = 320
4y = 320
y = 320 / 4
y = 80
therefore there are 80 books
so there are 3 x 80 = 240 magazines

Answer:
let the number of magzines be x
no of books=3x
according to the question
no of books +the no of magzines=320
now substituting the values
3x+x=320
4x=328
x=320/4
x=80
no of books =3x
=3*80
=240
there are 240 books
