Question

A library contains 60,000 books. 14,000 are the subject of business. 22,000 are on healthcare and and 12,000 on psychology and law . What percentage of the library books is on computing . If computing books make up two thirds of the remainder

Answer 1

The percentage of computing books is 13.33%.

Explanation:

The library consist of books on different subjects:

S = {Business, Healthcare, Computing, Psychology, Law,...}

There are a total of N = 60,000 books in the library.

Business (B) = 14,000

Healthcare (H) = 22,000

Psychology and Law (P&L) = 12,000

Remaining = N - B - H - P&L

= 60000 - 14000 - 22000 - 12000

= 12000

It is provided that computing books make up two thirds of the remainder.

Compute the number of computing books as follows:

C = 12000 × (2/3) = 8000

Compute the percentage of computing books as follows:

`C\% = (8000)/(60000)* 100=13.33\%`

Thus, the percentage of computing books is 13.33%.
