Explanation:

It the SP for both the Items is same and
there is a profit of x% and a loss of x%,
then the resultant loss = x²/100%
So, the resultant loss = 4%.
Total SP = 2.80, which is equal to 96% of CP of 2 books.
.: CP of 2 books = 2.80 × 100/96 = 2.92 (Appx);
:. Loss = 2.92 – 2.80 = .12 = 12 paise.
