One brother was utterly dumbfounded by their younger sibling’s Year 5 math exam results.

A Reddit user presented a perplexing question to students: how many pages are there within the confines of one book?

“Klein read 30 pages of a book on Monday and one-eighth of the book on Tuesday,” the question read.

“He completed the remaining quarter of the book on Wednesday. How many pages are there in the book?”

Some social media users found themselves immediately confounded by the question.

One person wrote: “And now we can all see why “Are You Smarter Than a 5th Grader?” worked as a game show.”

“Today I learned I would fail fifth-grade math,” another added.

Another person wrote: “I always think to myself; ‘Ugh. People should really be tested with basic skills before they’re allowed to go out into society.”

“And then I see this and realize I shouldn’t go out into society LOL!”

Some disagreed that the question was difficult.

“Not to be rude, but what is interesting about this,” one stated.

“It looks just like any other math problem that I’ve done in 5th grade.”

A Ph.D. holder in Engineering, specializing in Applied Mathematics, declared that figuring out the answer to Klein’s book wasn’t too difficult—provided one assumes he started it on a Monday.

To calculate one-eighth of the total, simply divide thirty pages by five; this equates to six.

If mathematics is your passion, the solution to this equation couldn’t be more straightforward. All you have to do is multiply eight by six and voilà – 48! Problem solved.
