Question

A bookseller bought a book for 15 and spent 5 on its binding. Then, he sold it for rs 24 . find his profit percentage.​

Answer 1

Answer:

Selling Price = Rs 100

Profit = Rs 20

Cost Price = SP - Profit = 100−20=80

Thus, Profit % = Profit/CP×100= 20/80 ×100=25 %

= 25%

Answer 2

Given that:

• C.P. (Cost Price) of the book = ₹15
• Overhead expenses = ₹5
• S.P. (Selling Price) of the book = ₹24

To find:

• Profit percentage.

Solution:

Total expenditure (or C.P.) on the book = Original C.P. + Overhead expenses

= ₹(15+5)

= ₹20

Now,

• C.P. = ₹20
• S.P. = ₹24

Clearly,

₹24 > ₹20

S.P. > C.P.

Therefore it is a profit.

We know that,

Profit = S.P. - C.P.

Profit = ₹(24-20)

Profit = ₹4

We also know that,

$\sf Profit \% = \dfrac {Profit}{C.P.} \times 100\%$

Substitute the values in the formula,

$\sf Profit \% = \dfrac {4}{20} \times 100$

$\sf Profit \% = \dfrac {1}{5} \times 100$

$\dag {\boxed {\bf {\pink {Profit \% = 20 \%}}}}$

Final answer:

The profit percentage of the bookseller on the entire transaction is 20%.
