Shreyas Singh from Podar International School, Pune
Class : Class 6
Should be 20 Kg. The mass of 3 balls together is 15 kg implies that weight of one ball is 5 kg. Now dog is equal to 30 kg since there are 6 balls on balance. So deducting mass of two balls which equals (5+5=10 kg), it will be 20 kg.
