I bought a pen for Rs. 5.50 and a notebook for Rs. 20.75 and paid the shopkeeper only Rs. 20. How much more should I pay the shopkeeper?
Amount paid to the shopkeeper =Rs. 20
Cost of a Pen =Rs. 5.50
Cost of note book =Rs. 20.75
Total bill =Rs. 5.50+Rs. 20.75=Rs. 26.25
Now, more amount to be paid to the shopkeeper
=Rs. 26.25−Rs. 20
=Rs. 6.25
Hence, Option D is correct.
