Question

A fruit vendor buys some oranges at the rate of Rs. 5 per orange. He also buys
an equal number of bananas at the rate of Rs. 2 per banana. He makes a profit
of 20% on oranges and 15% on bananas. At the end of the day, all the fruits are
sold out. If his total profit is Rs. 390, find the number of oranges purchased.

Answer 1

Step-by-step explanation:

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. Also, it is given that he makes 15 % on bananas.

Answer 2

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. Also, it is given that he makes 15 % on bananas.
