 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?

 Submitted by K Sengupta No Rating Solution: (Hide) The grocer should buy 15 packets, spending \$300. For a detailed explanation, refer to the solution submitted by Charlie in this location.
