The given pie-chart shows the various expenses (in per cent) incurred by publisher on publishing a book.
Question 150
For 11000 books the expenses incurred on others is Rs. 36960. If publisher wants a profit of 25%, then what should be the marked price (in Rs.) of each book ?
Solution
Amount spent on others for 11000 books = $$6\%\equiv Rs.$$ $$36,960$$
=> Total amount spent on publishing 11000 books = $$100\times\frac{36960}{6}$$
= $$100\times6160=Rs.$$ $$6,16,000$$
=> Amount spent on each book = $$\frac{6,16,000}{11000}=Rs.$$ $$56$$
$$\therefore$$ To get 25% profit, marked price of each book = $$56+(\frac{25}{100}\times56)$$
