Answer 1

I think the question is wrong. The original question is


Here three people buy different number of books which we don't know.

Given that 92.50 , 129.50 , 166.50 are the prices.
So we have to check the options in which is common factor of all these three prices.
We can find that 18.50 is a factor of all these.

18.50×5=92.50
18.50×7=129.5
18.50×9=166.5


So maximum price of one book is 18.50
