5% of books are in English,


10% of remaining books are in Hindi,


15% of remaining books are  in Sanskrit. 


Remaining books are in french = 11628


Calculation:


Let the total books in the library be 100%


According to question:


5% of books are in English


Remaining books = 100 - 5 = 95%


10% of remaining are in hindi = 10% of 95 = 9.5


Remaining books = 95 - 9.5 = 85.5%


15% of remaining books are in sanskrit = 15% of 85.5 = 12.825%


Remaining books = 85% - 12.825% = 72.675%


According to question:


72.675% = 11628


⇒ 1% = (11628/72.675)


⇒ 100% = (11628/72.675)× 100 = 16000


∴ Required value = 16000

Given information:
- 5% of the books are in English
- 10% of the remaining books are in Hindi
- 15% of the remaining books are in Sanskrit
- 11628 books are in French

To find:
The total number of books in the library

Solution:
Let the total number of books in the library be x.

Books in English = 5% of x = 0.05x
Remaining books = x - 0.05x = 0.95x

Books in Hindi = 10% of (remaining books) = 0.10(0.95x) = 0.095x
Remaining books = 0.95x - 0.095x = 0.855x

Books in Sanskrit = 15% of (remaining books) = 0.15(0.855x) = 0.12825x
Remaining books = 0.855x - 0.12825x = 0.72675x

Books in French = 11628

Therefore, we have the equation:

0.05x + 0.095x + 0.12825x + 11628 = x

0.27325x = 11628

x = 42534.71

Since the number of books must be a whole number, we round up to the nearest integer:

x = 42535

Hence, the total number of books in the library is 42535, which is closest to option (c) 16000.

DETAILED SOLUTION

let total no. of books be X

5%of X = X/20,no.of books in hindi

X-20/X=19X/20remaining books excluding books in hindi

19X/20×10/100=19X/200 no. of books in English

3rd step X-X/20+19X/200=171X/200no. of books excluding hindi and English books

171X/200×15/100=513X/4000 no.of books in sanskrit

X-X/20+19X/200+513X/4000=2907X/4000no. of books in French

2907X=11628×4000
=16000 total no. of books
