• Case 1=> Let total oranges are x;
  cp of 3 orangres=40 rs;
  cp of x oranges =40*x/3;
  
  case 2 => Similarly cp of x oranges =60*x/5;
  
  Therefore total cp =40*x/3+60*x/5=76*x/3
  
  And SP of 2x oranges =50*2x/3=100*x/3
  
  profit =(100*x/3-76*x/3)=24*x/3;
  Therefore profit %=24*100/76=31.5% ans.

• 1st orange: 40/3
  2nd orange: 60/5=12
  Total cost price: 12+40/3=86/3
  Selling price for 1 orange=50/3
  For 2 =100/3
  Profit= 100/3-86/3=14/3
  P%= 14/3 ÷ 86/3 *100= 16.2%
