Various expenditures incurred by a publishing company for publishing a book in 2018 are given in the following pie-chart. Study the chart and answer the question.

Price printed on a book is 15% above the cost price. If the price printed on a book is ₹942, then the cost of paper for a single copy in ₹ is (rounded off to one decimal place)

₹122.9

115% of cost price = 942

Cost price = \(\frac{100}{115}\) × 942 = 819.13

Cost on paper = \(\frac{15}{100}\) × 819.13

= 122.86

= 122.9
