### Books in a Library

In a library, 30% books are English books and 10% are Hindi books. If the remaining 3600 books are in Malayalam.

What is the total number of books in that library?

1. Nice and educative blog.

2. 100-30-10=60
3600/60=60
60*100=6000

3. for 60%---3600books
then40%---?
on cross multiplication=2400
hence total no. of books=3600+2400=6000

4. 6000 books

5. 6000 books

6. 100x3600/60=6000
a cool and educating blog.

7. 6000 books

8. 6000 books

9. 6000 Books,
60% of Books = 3600
30% of Books = 1800 (Half of above)
10% of Books = 600 (1/3 of above)

Total Books 6000

10. 3600 = 60%
2400 = 40%
Total = 6000 books

17. 9000 IS correct you would take the number of books you know 3600 times 100 for 100% then divide that by the % of book we don't know which is 40% to equal 9000

19. 10%-a
30%=b
3600=c

10%+30%+3600=100%
3600=60%
60=1%
6000=100%

20. 10% is 600 books
30% is 1800 books
60% is 3600 books
total= 6000 books

21. Total Number of books 6000
Already it mentioned 40% of other books, So remaining
3600 will be treated as 60%

then 10% means 600

English Books 30% means 1800
Hindi Books 10% means 600
Malayalam Books 60% means 3600
Total Number of Books are 1800+600+3600=6000

22. Total Number of books 6000
Already it mentioned 40% of other books, So remaining
3600 will be treated as 60%

then 10% means 600

English Books 30% means 1800
Hindi Books 10% means 600
Malayalam Books 60% means 3600
Total Number of Books are 1800+600+3600=6000

23. 3600.00 divided by 60% = 6000 books.

25. let n = total no. of books
n - .4n = 3600
.6n = 3600
n = 3600 / .6
n = 6000 total no. of books

26. 3600 x 40% -= 1440
1440+3600 = 5040
so that would mean 5040 books in library

27. 3600 x 40% -= 1440
1440+3600 = 5040
so that would mean 5040 books in library

28. 3600 is 60% of "x"
3600=.60x
3600/.60=x
6000=x

29. Total Books 6000

31. 100/60*3600 =6000

32. 3600 is 60%
3600/2=1800 is 30%
remaining percent is 10
3600/10=600
1800 english book
600 hindi book
3600+1800+600=6000

33. let X rep the total the total number of books in the library.
60/100 of X = 3600 (cross multiplying) you have, 60X = 360000,. X=360000/60 = 6000

34. 3600/60*100= 6000 books...

35. 2400 books are in that library, because the remaining 3600 books are in Malayalam.

36. x=.1x+.3X+3600
x(1-.1-.3)=3600
X=3600/(1-.1-.3)
X= 6000

37. 9600 total

38. x*60/100=3600
x=(3600*100)/60
x=60000

39. 7600 the total books

40. 30% Means 3000 books and 10% means 1000 books and remain 3600 the total is 7600 books

41. 6000 Books as 60%=3600 1%=60 books

42. 6000 books

43. 6000 total books

46. 3600:60% =x:40% then,
3600:0.60=x:0.40 in decimal
0.6x=1440
x=1440/.6
x=2400

ans: 2,400 total number of books in that library
since,the 3600 books are in Malayalam.
