\fontsize{18}{10}{\textup{\textbf{The cost price of the book is Rs. 63.}}}

Step-by-step explanation:  

Let the cost price of the book be Rs x.

The discounted price, after giving 10% discount on the marked price is

P_d=77-10\%\times 77=77-\dfrac{10}{100}\times77=77-7.7=69.3.

Since the bookseller gets 10% on the book, so we have

x+10\%\times x=69.3\\\\\Rightarrow x+\dfrac{10}{100}\times x=69.3\\\\\Rightarrow \dfrac{11}{10}x=69.3\\\\\Rightarrow 11x=693\\\\\Rightarrow x=\dfrac{693}{11}\\\\\Rightarrow x=63.

Thus, the required cost price of the book is Rs. 63.
