The printed price on a book is Rs.400,a bookseller offers a 10% discount on it . If he still earns profit of 12%,then the cost price of the book is?
a)Rs.280
b)Rs.353
c)Rs.360
d)Rs.300

• discount=10% (400)
  
  =40
  
  hence 400-40=360 is sp
  
  so, cp=100/(100+12)*360
  
  =321.4

• 10% of 400=40
  so,400-40=360(s.p)
  he earns a profit of 12%,
  so 1.12cp=sp
  =>1.12 cp=360
  =>cp=321.42 (NOT GIVEN IN OPTION)

• Marked price = Rs 400
  Discount of 10% = 0.1*400= Rs. 40
  Therefore new S.P is Rs.360
  He earns 12% profit :: therefore Rs.360*100/120= Rs.300

• 10% of 400=40 then book seller sold that book at the cost of 360
  12% of 360=43.2 then 360-43=317 so cost price of the book = 317

• SP=90% of 400=320
  12%=PROFIT
  CP=(100/112)*320=285.71
• 7 years agoHelpfull: Yes(2) No(11)
• s.p of book=400
  discount is 10%=90*400/100=360
  s.p=360
  we know s.p=g%*100
  360=120*c.p/100
  c.p=360*100/120
  c.p=300.

• 10 % of 400 is 40 so sp is 360 so the anser is around 300
• 7 years agoHelpfull: Yes(1) No(2)
• Here it is said that the SP initially is Rs400.
  Now 10% discount on SP = Rs 40
  so the current SP becomes 400-40 = 360
  No ,
  C.P = ((100)/(112))*360 = 321.42 appx(Ans)

• s.p=400(90100)=360
  c.p=100(120(360)=300
  note:12% is take it as 20%

• discount is 10%(400) => 40
  s.p= 400-40=360
  so, profit of 12% of c.p is s.p
  => 12/100 c.p = 360 => 300

• Let us assume book C.P = Rs. X
  
  Given printed price = Rs 400
  Bookseller offer discount of 10% = 0.1*400= Rs. 40
  Therefore new S.P = Rs.360
  Condition: He still earn profit of 12%
  => x*120/100 = Rs. 360
  => x = Rs.360*100/120= Rs.300

• Lets assume book CP = Rs. X
  
  Given printed price = Rs 400
  Bookseller offer discount of 10% = 0.1*400= Rs. 40
  Therefore new S.P = Rs.360
  Condition: He still earn profit of 12%
  x*120/100 = Rs. 360
  =>x = Rs.360*100/120= Rs.300

• firstly S.P=400 and discount=10%
  S.P now becomes=400-(400*(10/100))
  S.P=360
  instead of 12% if u would have placed 20% then the ans is 300
  by evaluating S.P=((100+profit)/100)*C.P
  360=(120/100)*C.P
  C.P=300

• 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% .
  
  ∴ = Rs. 360
  
  x = Rs. = Rs.300
