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?

₹1,167

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
