Question

A shopkeeper has some 100 gm weights and some
500 gm weights. He can weigh a maximum of 8 kg
in one weighing. If he has 20 weights, what is the
maximum weight that he can weigh using only the
100 gm weights?​

Answer 1

Answer:

You are a shopkeeper who is selling sugar between 1-100 kg .Now you have to design 5 weights in such a way that any integer weight between 1-100 can be measured in a single attempt ,without using more than 5 weights.You can't repeat weights.

He gave me time like 1 hour to figure it out, and i tried it as hard as i could. But finally i couldn't figure out more than this that weights have to be distributed on both sides of measurement.

Does anybody have some clue as what could be the answer.
