Puzzle : In a factory, there are 10 machine which produces exactly 1 kg of sugar box. But unfortunately 1 machine among them is defective and produces 900 gm sugar box. How you find the defective one?

Note: You are not allowed to mark machine or arranging them in a sequence. You are allowed to use weighing machine only once.

Solution:
We will pick 1 packet from Machine A, 2 packet from Machine B, 3 packets from Machine C and so on till 10 packets from Machine J. Now we will weight all packets if the quantity is 300 grams less it means there is defect in Machine C
