Let the original price of a book = x Rs.
So, the increased price = x+10 Rs.
With the original price , the number of books that can be bought for Rs. 1200 is 1200/x
With the increased price the number of books that can be bought for Rs. 1200 is 1200/(x+10)
Acc to question,
Solving by quadratic factorisation we get,
So original price =Rs.30
