let the number of oranges purchased be x.
cost of 1 banana=Rs.2
cost of x bananas=R.2x
profit=Rs.15% of 2x=Rs.3x/10
total profit=Rs.390
x=390*10/13=300
ans:number of oranges purchased=300
cost of 1 banana=Rs.2
cost of x bananas=R.2x
profit=Rs.15% of 2x=Rs.3x/10
total profit=Rs.390
x=390*10/13=300
ans:number of oranges purchased=300
