Question

Answer 1

Let B=books & M = magazines

By question, B+M=320.....(1)

Also, M=3B.....(2)

From (1) & (2),

B+3B=320

Or,B=320/4=80

Now, M=3B=3×80=240

Therefore there are 80 books and 240 magazines

Answer 2

There are 240 books and 80 magazines

Step-by-step explanation:

Let the no. of magazines be x

We are given that  there are three times as many books as magazines

So, No. of books = 3x

We are given that there are 320 books and magazine altogether in a book shop

So, $x+3x=320$

$4x=320$

$x=\frac{320}{4}=80$

No. of books = 3x=3(80)=240

Hence There are 240 books and 80 magazines
