A shopkeeper charges ₹1.50 to photocopy a sheet of paper and a discount of 5.5% is given on all photo copies done after 400 sheets. How much will it cost to photocopy 800 sheets of paper?
Answer & explanation
Correct answer: option 1
Total number of sheets = 800
The cp = 1.50 to photocopy a sheet of paper
A discount of 5.5% is given on all photocopies done after 400 sheets
Cost to photocopy next 400 sheets = 400 × 1.50 = Rs. 600
Cost to photocopy after 400 sheets = 400 × 1.50 × \(\frac{94.5}{100}\) = 6 × 94.5 = 567
Cost to photocopy 800 sheets of paper = 600 + 567 = 1167
