Question

A fruit vendor 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 20% profit on oranges and a 15% profit on bananas. At the end of the day, all the fruit is sold out. His total profit is ₹390. Find the number of oranges purchased.​

Answer 1

Answer:

300

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.
