Answer:
Rahul is left with ₹72.10.
Explanation:
Rahul initially had ₹500. If she spent ₹427.90 on a book, we have to subtract the amount she spent from the amount she originally had to find out how much money she has left. So, 500 - 427.90 equals ₹72.10. Therefore, after buying the book, Rahul is left with ₹72.10.
