Question

A fruit-seller bought 25 kg apples at 8 per kg and 30 kg apples at 10 per kg. At what rate per kg should he
sell them to gain 21%.
​

Answer 1

$\Huge \fbox \green{Solution}$

Fruit Seller bought 25 kgs apples at 8 Rs/kg i.e. , for 25 * 8 = 200 Rs.

and bought 30 kg apples at 10 Rs/kg i.e., for 30*10 = 300 Rs.

So, the Cost Price of 55 kg apples (CP) = (200+300) Rs = 500 Rs.

Profit percent to be made after selling fruits = 21%

Profit = (Profit% / 100) * CP

Profit = (21 / 100 )* 500 = Rs. 105

Selling Price = Cost Price + Profit = (500 + 105) Rs.

Selling Price of 55 kg apples (SP) = Rs. 605

So, Selling price of 1 kg apple = Rs. ( 605/55) = Rs 11

Therefore, the fruit seller should sell the fruits at the rate of 11Rs per Kg to gain profit of 21%.

Answer 2

Answer:

21 Precent

Step-by-step explanation:

S.P.=$230

P =15 percent

profit=15/100×230

= 34.5

C.P. = 230-34.5

= 195.5

Apple 25 Kg = Rs 8/Kg

25 = 25×8

= 200

Total C.P = 200+300

= 500

Gain = 21 per cent
