The printed price on a book is 400, a bookseller offers a 10% discount on it. If he still earns a profit of 12&, the CP of the book is
a) 280
b) 352
c) 360
d) 300

• S.P= 360 Rs.
  If Profit = 12% then 1.12*C.P = S.P
  1.12*C.P = 360
  C.P= 321.43 Rs.
  And If Profit=12 Rs. then C.P= 348 RS.
  As there is ambiguity in question.

• sp=400*.90=360
  we know that,
  profit=sp-cp
  so,
  cp=sp-profit
  360-12=348(ans)...
  options are incorrect....

• printed price of a book is 400
  10% of 400 is 40
  now S.P is 400-40=360
  
  assuming 12 as a unit price
  cp=360-12=348
  
  assuming 12 as a percentage
  cost of book c.p=100/(100+gain%)*S.P
  C.P=(100/120)*360
  c.p=300

• 400 is M.P
  and 10% discount (400-40(10% of 400))=360.
  C.P=((100/100+gain %)*S.P)
  C.p=((100/112)*360)=321.4.
  that is ans but not given the option so near by 300 so
  ans d is correct

• sp=400*(90/100)=360
  cp=360-12=348

• as given 10 % of 400 =40
  so the book will be 400-10=360
  so on selling the book for 360 still the bookseller got 12 % profit
  cp=(100/100+profit%)*cp
  (100/112)*360
  =321.428

• the Printed price is clearly a Marked Price, as it is been printed for the haggle free C.P
  as S.P=M.P*(100-discount)%
  S.P= 400*(90)/100=360
  now as, profit=12
  Profit=S.P-C.P
  
  C.P= S.P- Profit
  C.P= 360-12
  348 not in option
  but if i take profit as %ge, it is somewhat nearer to 359.56 as C.P
  so, C will be correct!

• DATA GIVEN IN QUESTION IS WRONG 12 should be 20 %.
  
  S.P= 360 Rs.
  If Profit = 12% then 1.12*C.P = S.P
  1.12*C.P = 360
  C.P= 321.43 Rs.
  And If Profit=12 Rs. then C.P= 348 RS.

• Lets Rs x be the cost price of book.
  
  Given, printed price = Rs 400
  
  Bookseller offer discount of 10% = 0.1 × 400= Rs. 40
  
  Therefore, new selling price = Rs. 360
  
  
  Condition given : He still earn profit of 12% .
  
  ∴ x times frac{120}{100}x×
  100
  120
  ​
  = Rs. 360
  
  x = Rs. 360 times frac{100}{120}360×
  120
  100
  ​
  = Rs.300
