Monalisa Sarkar  (10 years ago)

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.

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

manikandan  (7 years ago)

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

balaji singh  (5 years ago)

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

Ankit  (9 years ago)

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
