Hi Dinesh,
First no. each machine as 1, 2, ,,, 10 and then take as many balls from each machine as per the no. of the machine.
Now weigh them together. the total weight will be 10+20+30+...+100 = 550 grams in reality if there would have been no error in any of the machines. If the weight comes as 549 then machine one is defective, if weight comes as 548 then machine two is defective and so on till weight comes as 540 then machine ten will be defective.
