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 = $$56+(\frac{25}{100}\times56)$$

= $$56+14=Rs.$$ $$70$$

=> Ans - (C)
