My sister spent 32 days reading a story book about math problems in grade five. As we all know, my sister reads four pages more than her sister every day. I asked my sister how many books she read every day. Did you read the question wrong?

It takes 24 days for my sister to read a story book and 32 days for my sister to read one. As we all know, my sister reads four pages more than her sister every day. How many pages does my sister read every day?

I have read such a question. If it is the following question, it should be calculated like this:

4-1/24-1/32-384-384-32 =12 pages.
