A bookstore stocks of its books as fiction works, and less t [#permalink]

Hey,

So you missed out on wordings.
\(\frac{1}{3}\) less than the fiction books means that the self-help books are \(\frac{2}{3}\) of the fiction books.

For ex.
Let's say fiction books are \(60\). So self-help books = \((1 - \frac{1}{3}) * 60 = \frac{2}{3}* 60 = 40\)

Please ask if the doubt remains.

When calculating the number of self-help books why did you did x/5 - (1/3)*(x/5) and not x/5 - (1/3). It just says 1/3 less than the fiction books so this seems valid to me. But I couldn't get the correct answer. What am I missing?

Re: A bookstore stocks of its books as fiction works, and less t [#permalink]
simple soln:

Let total books be 15, 1/5th of total books is fiction that makes it 3
For self help books it becomes: 3 - (1/3) *3 = 3-1 = 2

Therefore 3 + 2 = 5
Ans : 5/15 equals 1/3
