"Meenu" buys a book for Rs. 270 and sells it at a profit of 10% . How much does she sell it for?​

Answer 1

Answer:

The cost of a book =Rs.275

The cost of a book =Rs.275Loss percent =15%

The cost of a book =Rs.275Loss percent =15%Loss=Loss % of C.P =15% of Rs. 275

The cost of a book =Rs.275Loss percent =15%Loss=Loss % of C.P =15% of Rs. 275= 100/15 ×275=Rs.41.25

15 ×275=Rs.41.25Therefore, S.P = C.P - Loss

15 ×275=Rs.41.25Therefore, S.P = C.P - Loss=275−41.25=Rs.233.75

15 ×275=Rs.41.25Therefore, S.P = C.P - Loss=275−41.25=Rs.233.75Hence, Amina sells a book for Rs. 233.75

Answer 2

$Cost \: of \: Book = Rs.270$

$Profit = 10 \: \%$

$Profit = Profit \: \% \: of \: s.p$

$= \frac{10}{100} \times 270$

$= rs. \: 27$

$S.P = C.P + PROFIT$

$S.P = 270 + 27$

$S.P = 277$
