Question

I bought a number of books one day, four times of them on the next day, and eight the

third day. In all I bought 38 books. How many books did I buy the second day?

Answer 1

24 books dude because
let books on first day back is = X
then second day= 4x
third day= 8
total is =X+4x+8=38
then
5x+8=38
5x=30
X=6
so number of books on second day = 4x=4×6=24
