Question

raghu bought 80 oranges at 3Rs per orange. he sold 30% oranges at 5Rs each and remaining oranges at the rate of 3Rs each. find his profit or loss per cent​

Answer 1

Answer:

20% Profit percentage

Step-by-step explanation:

Since Raghu bought 80 oranges at 3Rs each, his total expense (E) is:

$E= 80*3 = 240$

Now for his earnings, he sold 30% of the oranges for 5Rs each and 70% for 3Rs each. Therefore, his earnings are represented by the following expression:

$P = 80*0.3*5 + 80*0.7*3\\P=288$

His profit percentage (%) can be found as follows:

$\%= \frac{P - E}{E}*100\\\\\%= \frac{288 - 240}{240}*100\\\%= 20\%$
