Question

A shopkeeper purchased 25 dozen oranges at the rate of 500 per hundred and sold them at the rate of 640 per hundred in the whole transaction how much profit percent did he make

Answer 1

Total CP = 25×12×500/100=1500
Total SP = 25×12×640/100= 1920
Profit = SP - CP = 420
Profit percent = 420/1500×100= 28percent

Answer 2

Profit% = 28%

Given:

A shopkeeper purchased 25 dozen oranges at the rate of 500 per hundred and sold them at the rate of 640 per hundred.

To find:

In the whole transaction how much profit percent did he make?

Solution:

First, we will calculate total oranges purchased.

1 dozen = 12

Total oranges purchased = 25 dozen = 25*12 = 300

Now, we will calculate cost price of 300 oranges.

Cost price of 100 oranges = 500

Cost price of 1 orange = 500/100 = 5

Cost price of 300 oranges = 5*300 = 1500

Now, we will have to calculate selling price of 300 oranges.

Selling price of 100 oranges = 640

Selling price of 1 orange = 640/100

Selling price of 300 orange = 640/100 * 300

= 640 * 3 = 1920

Now, we have to calculate profit as SP is more than CP

Profit in whole transaction = Total selling price - total cost price

= 1920 - 1500

= 420

Now, we have to calculate profit percentage.

Profit % = Profit/ CP * 100

= 420/1500 * 100

= 28%

Hence, profit percentage in whole transaction is 28%.
