(1) Rs 12 (2) Rs 14 (3) Rs 16 (4) Rs 20 paise 60​

Answer 1

$\Large\underline{\underline{\sf{Given}:}}$

• Discount % = 10 %
• SP of book = Rs.12.60

${\large\bf{\mid{\overline{\underline{To\:Find}}}\mid}}$ :-

• MP of the book ?

$\Large\bold\star\underline{\underline\textbf{Formula\:used}}$ :-

• MP = SP * 100 / (100 - Discount%)

$\huge\star{\underline{\tt{\red{Answer}}}}\star$

Putting values in above told formula we get,

→ MP = (12.6 * 100) / (100 - 10)

→ MP = (1260) / 90

→ MP = Rs.14 (Option 2). (Ans.)

Hence, The Printed Price of the book was Rs.14.

$\boxed{\begin{minipage}{7 cm}\boxed{\underline{\underline{\bigstar\:\bf\:Extra\:Brainly\:knowlegde\:\bigstar}}}\\\\1) Profit = SP - CP\\\\2) Loss = CP - SP\\\\3) Profit\% = (Profit in Rs.)*100/CP\\\\4) Loss\% = (Loss in Rs.)*100/CP\\\\5) SP = CP*(100+P\%)/100\\\\6) SP = CP*(100-L\%)/100\\\\7) CP = SP*100/(100+P\%)\\\\8) CP = SP*100/(100-L\%)\\\\9) Discount = MP - SP\\\\10) Discount\% = (Discount in Rs.)*100/MP\\\\11) SP = MP*(100-D\%)/100\\\\12) MP = SP*100/(100-D\%)\\\\\end{minipage}}$

$\rule{200}{4}$

Answer 2

Answer:

Ok dear user . This is your answer

l hope you would like it.

Step-by-step explanation:

firstly

Given that-:

after discount the cost of the book is-Rs 12 and 60paise that is -Rs12.60

Discount - 10%

so ,

Let the actual price of the book = X

then ,10% of X- X= 12.60 rs

Therefore

10/100 × X - X= 12.60rs

1/10 × X- X=12.60rs

X/10 -X =12.60rs

X/10 - X/1=12.60rs

then by doing LCM the left side statement that is what in left side of equals to changes to

X-10X/10=12.60rs

9X/10=12.60rs

then the 10 that is under division came to left side and become multiplication and multiply by 12.60rs and the product will be 126.00 rs

then the 9X's. 9 goes to devide with 126.00 rs because it was under multiplication .

9X=126.00rs

X= 126.00/9

and the final product after division is Rs 14

then your answer Will be

(2)rs 14.

so that's it

If anything went wrong that I am so sorry for that.

thank you for asking question.

be safe and be happy..
