Hi Sarojit Auddya,
As mentioned in question, must carry atleast one book each of management, mathematics, physics and fiction.
Hope this helps!

Hi Asher,
In this type of question, you need to maximise the point.
If you select a management book, you need to select at least 2 fiction books, which implies the total point scored from the three books is (4*1+1*2) = 6
Similarly,
If you select a mathematics book, you need to select at least 2 physics books, which implies the total point earned from the three books is (3*1+2*2) = 7.
Hence, we need to maximise mathematics and physics books as much as possible. (for the same amount of books, the math-phys combo gives us more points).
We need to select atleast 1 management book, which implies that we need to select atleast 2 fiction books as well. Hence, we will select 1 management and 2 fiction books.
Hence, the remaining books are (10-3) =7.
We can select 2 maths books and 5 physics books from this. (1 math 2 Phys), and (1 math, 3 Phys).
Hence, the maximum point earned (4*1+1*2+3*2+2*5)=22
Hope this helps!

but the correct ans given is 22.

you have mistakenly typed 21 as total

Hi Parth,
Yes, You're correct! Please check the modified explanation. Please let me know if you have any other queries.

Hi Meghna,
The question states that he must carry two or more fiction books for every management book he carries. So, for 2 management books, there should be at least 4 fiction books, but that is not the case with your solution, as he only has 2 fiction books. So your case does not follow all the conditions.
Hope this clears your doubt!

Hi Ajay,
It does not satisfy the condition ' I must carry at least one book each of management, mathematics, physics and fiction. '
Hope this helps.

Hi Angira,
This violates because the bag can carry only 10 books.

Hi Rishu,

Based on the constraints, we first selected the number of books to be taken, and then based on the points we selected the combination of these books in order to maximize the points.

Hi,It is given that for every 1 math book you need to carry at least 2 physics books. Thus for 3 math book, you need to carry at least 6 physics books. Your solution violates that rule. Hope it helps

Hi Anshit,
For every maths book, there must be two or more physics books. Thus, this case is invalid as there are only 2 physics books for 2 maths books.
I hope this helps. Feel free to ask any questions if the doubt persists. Regards.

Hi Sameer,
In point 3, it is given that at least one player between Bablu and Gautam must be selected.
Therefore, the team that you have mentioned contradicts point 3.
I hope this helps!

Hi Nandani,
We do have a concept video on maximization - you can access it here: https://cracku.in/cat/lesson/2859/maxima-minima-di
With regard to the above set, please let us know if you had trouble understanding any specific part of the question or explanation - we are happy to assist!

Hi,
It is given that for every management book I carry, I must carry two or more fiction books.
But in your case, you're carrying one management book and one fiction book, which is not valid.
For every management book => at least 2 fiction books in the bag
I hope this helps! Please let me know if the doubt still persists.
