15% for travel
Hence amount left with him is Rs. 85/-
Each pencil costs Rs. 4/-
Hence for 5 pencils it is Rs. 20/-
Amount left with him is Rs. 65/-
Each book costs Rs. 6.6/-
Hence he can buy 9 books with the remaining money.

pencil = 4Rs  book = At most 6Rs    bcoz if book is Rs7, he cannot buy 15 books with 100 Rs.

traveling expenses = 15Rs, 4 pencils = 20Rs

eventually It remains 65Rs so ans= Rs10

(100-15-4*5)/(100/15)=65*15/100=9.75

But you cannot buy 10, so it should be 9.

Given the data, the man can buy 4 pencils and at most 6 books with some balance because the number of books that he can buy remains a fraction, i.e, 20/3 .
15/- is kept for travelling expenses and so 68/- remains with him.
now he can either buy 85/4= 21.25 i.e, 21 pencils or
85/(20/3) = 12.75 i.e, 12 books.

He kept 15% for the travelling means Rs.15
remaining money=100-15=85.
he can puchase 25 pencil or 15 books in Rs.85.
if 25 pencil in 85
then
5 pencil in 5*85/25=17
remining money =85-17=68
he can purchase 15 books in just 85
then books in Rs 68  =15*68/85=12

25 pencils -> 100
5 pencils -> 20
money he has 100-15=85
money left after buying pencils 85-20=65
100-> 15 books
65 -> it comes up to something slightly less than ten.
so 9 is the ans.
