Question

A fruit vendor buys some oranges at thr 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 20% profit on oranges and 15% profit on bananas. At the end of the day, all fruits are sold out. his total profit is RS 390. Find the number of oranges purchased.

Answer 1

let the no. of oranges purchased be x.

cost price of oranges=5x.

he buys equal no. of bananas.

so no. of bananas=x.

cost price of x bananas=2x.

Now, he makes a profit of 20% on oranges.

therefore, selling price of oranges=5x+20%of 5x

  =6x

profit on oranges=6x-5x=x

he makes a profit of 15% on bananas

therefore, selling price of bananas=2x+15% of 2x

  =23x upon 10

profit on bananas=23x /10-2x=3x /10

Total profit made =x+3x /10=13x /10

According to ques,,,  13x /10=Rs 390

therefore x=300
