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

20% Profit percentage

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:

`\%= (P - E)/(E)*100\\\\\%= (288 - 240)/(240)*100\\\%= 20\%`
