70% on books which is $35. So the answer is 35 .
Answer:
<em>Number of story books bought = 100
</em>
<em>
C.P. of each book = Rs. 135
</em>
<em>
C.P. of all 100 books = Rs. (135×100)= Rs. 13500
</em>
<em>
C.P. of 90 books = Rs. (135×90)= Rs. 12150
</em>
<em>
Number of books donated = 10
</em>
<em>
Number of books sold = 100-10=90
</em>
<em>
Loss% in the transaction = 2%
</em>
<em>
S.P. of all books = (C.P./100)(100-loss%)
</em>
<em> =Rs. (12150/100×98)
</em>
<em>
Thus, S.P. of each book
</em>
<em>
= Rs. {(12150/100×98)÷90}
</em>
<em>
= Rs. (12150/100×98/90)
</em>
<em>
= Rs. 132.3</em>
