A farmer called his five sons and distributed the some oranges among them as below: 1st: 100 oranges 2nd: 80 3rd: 60 4th: 40 5th: 30 Then the farmer asked his son to go to five different places to sell the oranges. The conditions set are: 1. They can not redistribute the oranges. 2. All oranges should be sold at same rate. 3. Final collection should be equal for each. Now what is the rate offered and final collection?
