A magazine tested different microwave ovens and rated them on their ease of use, energy efficiency, quietness, and ability to heat food evenly. The ratings in each category ranged from 1 (poor) to 5 (excellent). The following table shows the magazine’s ratings.
Assume that, in the price category, a lower price constitutes a higher rating. For each of the following pairs of characteristics, select Yes if exactly one of the listed microwaves has the highest rating in both characteristics. Otherwise, select No.

Given: a lower price constitutes a higher rating.
1. Price and energy efficiency - No, as when we look at the table, we can see that the brand of microwave with the lowest price, does not have the highest efficiency.
2. Energy efficiency and ease of use - No, again the brand of microwave with the highest Energy efficiency does not have the highest ease of use or vice versa.
3. Heating evenness and ease of use - Yes, as we can see from the table, that the brand: Micro GX has the highest value in both the categories.

3. Heating evenness and ease of use - Yes, as we can see from the table, that the brand: Micro GX has the highest value in both the categories.
1)No,since the brand with lower price doesn't have Highest efficiency
2)No,Brand with highest energy efficiency does not have Highest ease of use or vice versa
3)Yes,Micro GX has highest value of heating evenness and ease of use
2) Heatwave 380 is the straight winner since it satisfies all the criteria mentioned by the buyer and Luxo premium has price =280,which is greater than 250,so rejected and Micro GX has price(350) greater 250 ,so rejected
2)No,Brand with highest energy efficiency does not have Highest ease of use or vice versa
3)Yes,Micro GX has highest value of heating evenness and ease of use
