Suppose you buy a bottle of honey and a biscuit packet.

Solution:

While buying a bottle of honey or a biscuit packet, the logo or mark one will have to look for is ISI or Agmark. These are logos certifying the quality of goods in the market. Only those producers are allowed to use these marks who follow certain quality standards set by the organisations issuing these certifications. Thus, if a bottle of honey or a biscuit packet has one of these logos on it, then it implies that the product is of good quality.
