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.

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

Official Explanation

1. 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.

Explanation

Price and energy efficiency

Sorting the table on Price reveals that only the Luxo Economy microwave has the lowest price (€170) and thus, given the assumption stated in the text, the highest rating for price. Sorting the table on Energy efficiency reveals that the InstaCook CM-2000 microwave has the highest rating (5) for energy efficiency while the Luxo Economy has the lowest rating (1). Therefore, none of the listed microwaves has the highest rating in both characteristics.

The correct answer is No.

Energy efficiency and ease of use

Sorting the table on Energy efficiency reveals that only the InstaCook CM-2000 microwave has the highest rating (5) for energy efficiency. Sorting the table on Ease of use reveals that three microwaves have the highest rating for ease of use (Micro GX, Heatwave 380, Superchef Platinum) while the InstaCook CM-2000 has a lower rating (3). Therefore, none of the listed microwaves has the highest rating in both characteristics.

The correct answer is No.

Heating evenness and ease of use

Sorting the table on Heating evenness reveals that only the Micro GX microwave has the highest rating (5) for heating evenness. Sorting the table on Ease of use reveals that exactly three microwaves have the highest rating (5) for ease of use (Micro GX, Heatwave 380, Superchef Platinum). Therefore, exactly one of the microwaves listed, the Micro GX, has the highest rating in both characteristics.

The correct answer is Yes.
