Question

The cost price 13 books is equals
to the selling price of 10 books. Find
the profit percent.​

Answer 1

Answer:

Profit percentage = 30%

Step-by-step explanation:

Let the C.P of 1 books be Rs.x

Then,

C.P of 13 books = Rs.13x

Now, according to the Question,

S.P of 10 books = C.P of 13 books

S.P of 10 books = Rs.13x

Here,

Since the C.P is given for 13 books and S.P for 10 books, Quantities are not balanced.

Profits/Loss can only be found out for equal things.

So,

C.P of 10 books = Rs.10x

Now,

Profit = S.P - C.P [of 10 books]

P = 13x - 10x

P = 3x

Profit % = (Profit/C.P) × 100

P % = (3x/10x) × 100

P % = (3/10) × 100

P % = 0.3 × 100

P % = 30%

Hence,

Profit percentage = 30%
