price of 1 pencil=100/25=4
price of 1 book= 100/15=20/3
for travelling expenses=rs15(15%of100)
remaining amount=rs85
cost of 5 pencils=4*5=20
now remaining amount=rs65
in 1rs ---------- 3/20 books can purchased
so in rs65 -------- 3/20*65=39/4=9 3/4
so 9 books he can purchase with remaining money.

total money in the pocket=100
with 100rs the person can buy 25 pencils ----------each pencil cost=100/25=4rs
with 100rs the person can buy 15 books ------------each book cost= 100/15=20/3
traveling expences= 15% of 100rs=15rs
remaining total money=85rs
he brought 5 pencils cost of 5pencils=5*4rs=20rs
net balance=85-20=65rs
with 65rs how many books we can brought
i.e, 1 book =20/3rs
xbooks=65rs
criss cross the above equations x*(20/3)=65*1
x=65*(3/20)
x=39/4 i.e, nearly equal to 40/4
if shop keeper is kind we get 10 books.
else if shop keeper is conjus we get 9 books only.

he has bought 5 pencil , so he has money to buy 10 pencil more.

price of 25 pencil= price of 15 book
1 pencil =15/25
10 pencil=15/25 * 10 = 6 book
so , by the remaining money he can buy 10 pencil or 6 book.

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.
