ChatGPT cannot solve math problems?

According to a test done by someone in the US, ChapGPT cannot solve a simple Grade 5 math problem. I am not surprised, as it is not built for math, it is an AI language model. 

Anyway, here's the problem posed to ChatGPT:

Q:  Klein read 30 pages of a book on Monday and 1/8 of the book on Tuesday. He completed the remaining 1/4 of the book on Wednesday. How many pages are there in the book?

Here's the answer from ChatGPT, after a long few minutes!

Let's represent the total number of pages in the book by "x".

Klein read 30 pages on Monday, so the remaining number of pages in the book is (x - 30).

On Tuesday, he read 1/8 of the book, which is (1/8)x pages. So the remaining number of pages in the book after Tuesday is (x - 30 - (1/8)x) = (7/8)x - 30.

On Wednesday, he completed the remaining 1/4 of the book, which is (1/4)(7/8)x = (7/32)x pages.

Since Klein completed the entire book on Wednesday, we can set up an equation:

(7/8)x - 30 - (7/32)x = x

Simplifying this equation, we get:

(21/32)x = 30

Multiplying both sides by (32/21), we get:

x = 45.71 (rounded to two decimal places)

Therefore, there are approximately 45.71 pages in the book.

A simple solution made complex!!! What is your answer? 48?
