Explanation: First, measure 1 kg of wheat. Then transfer the 1 kg to the other side with the weight. Doing this lets u weigh 2 kg of wheat. Then transfer and repeat so you can measure 4 kg. Then 8kg the 16 kg then 32kg and lastly 64kg. That gets 6 operations. But you have to find 63 so measure 1 kg and take that off. That makes 7 operations.
