Answer:

20% Profit percentage

Step-by-step explanation:

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

[tex]E= 80*3 = 240[/tex]

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:

[tex]P = 80*0.3*5 + 80*0.7*3\\P=288[/tex]

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

[tex]\%= \frac{P - E}{E}*100\\\\\%= \frac{288 - 240}{240}*100\\\%= 20\%[/tex]
