As per the questions,
14 notes of Rs10...so person can contribute Rs10 note in 14 ways.if person dont give Rs 10 note then number of ways of contribution are 14+1=15.
9 notes of Rs 5...so person can contribute Rs5 note in 9 ways.if person dont give Rs 10 note then number of ways of contribution are 9+1=10.
and so on..
SO the number of ways can be contribute to a charitable fund 15*10*5*8-1=5999(option b) answer
here -1 is used because person must have to use atleast one note.
Here SANDEEP is correct..

14 notes of Rs.10 can be distributed in 14 ways....but there is also a way in which the person distributes no rs 10 notes.
so.....14 notes can br distributed in (14+1) = 15 ways........
similarly,,,,,9 notes of Rs 5 ,4 notes of Rs 2,and 7 notes of Rs 1 can be distributed in (9+1) ,(4+1) and (7+1) ways respectively.
Hence,Total ways are----15*10*5*8==6000...But,,This also includes a way in which none of the notes of any kind has been distributed.

So,The final result will be::(6000-1) i.e 5999!!!!!!!!!!1
