Question

A tea factory has a certain number of packers all of whom pack 1 kilo

unmarked boxes filled with tea. Each packer fills each box with exactly

1 kilo of tea. One of the packers consistently steals 10g of tea from

each box he/she packs. The manager knows that the culprit is one of the

packers but he doesn’t know which one. As he is trying to work out how

to unmask the culprit a porter is wheeling an electronic weighing

machine through the factory. The manager asks the porter if he can use

the machine to help solve his dilemma. The porter replies that the

machine is for another department but reluctantly agrees the use of the

machine for only one weighing/reading only. Using the weighing machine

once to take one reading the manager is able to unmask the culprit. How

does he do it?
