Question

A fruit seller buys some oranges at the rate of ₹ 5 per orange. He also buys an equal
number of bananas at the rate of ₹ 2 per banana. He makes a profit of 20% on oranges and a profit of 15% on bananas. In the end, he sold all the fruits. If he
earned a profit of ₹ 390, find the number of oranges.

Answer 1

Answer:

Since the rate of oranges is Rs 5 per orange and the rate of bananas is Rs 2 per banana, he spent Rs 5x on oranges and Rs 2x on bananas. It is given that he makes 20 % on oranges. So, from formula (1), the total profit on oranges is 20(5x)100=x.

Answer 2

Answer:

300 is the answer

Step-by-step explanation:

Let the no. of oranges =x= no. of bananas

cost price =5x+2x=7x

Gain on oranges =20/100×5x=x

Gain on Bananas = 15/100×2x=0.3x

Profit ⇒1.3x=390

⇒x=390/1.3=300

No. of oranges purchased =300.
