 Slippery Supplier (Posted on 2013-11-12)
A grocer has six suppliers with each supplier selling a different brand of tea in 4-ounce packets at \$ 20 per packet. The grocer knows that one of the suppliers gives short weight, each packet of his brand weighing only 3.75 ounces.

Using a digital scale with only one weighing, what is the minimum amount the grocer must spend to be sure of finding the supplier who gives short weight?

 Corrected for 6 supp. --thanks, Steve! | Comment 3 of 6 |
Cut,paste and modify for 6 suppliers:

He should buy 15 packets , 1 from supplier A, 2 from supplier  B
and 3 from  supplier  C, 4 from supplier  D, 5 from supplier  E

If the total weight is 60 oz, then F is the cheater,
If the total weight is 59.75  oz, then  A is the cheater,
If the total weight is 59.50 oz, then B  is the cheater,
If 59.25 oz, then C    etc

Total cost: 15*20=300\$
