Question

A library has 500 books. There were history, maths and science books. The ratio of the history to maths

to science books is 2:3:5. If 20 history, 40 maths, and 10 science books were added in the library,
find the new ratio of the history to the maths to the science books.

Pls help

Answer 1

The new ratio of the history to the maths to the science books would be 22:43:55. With the addition of 20 history, 40 maths, and 10 science books, the total number of books in the library is now 570. The new ratio of the history to the maths to the science books is therefore 22:43:55.
