Hint:
Unit rate of purchase of a brand refers to the rate of 1 short offered by a particular brand.
Unit rate = Total cost/ Number of shorts.
Best Unit price of purchase will be determined by calculating Unit price offered by all 3 brands and selecting the one with least price.
The correct answer is: 3
Given-
For Mart X- A. Total Cost = $ 48 and Number of shorts = 12
For Mart Y- A. Total Cost = $ 72 and Number of shorts = 24
For Mart Z- A. Total Cost = $ 70 and Number of shorts = 14
To find- Best Unit Rate of purchase
Solution-
Unit Rate for Mart X = Total Cost / Number of shorts
∴ Unit Rate for Mart X = $ 48 / 12 ....................... (As per given information)
∴ Unit Rate for Mart X = $ 4 per short
Unit Rate for Mart Y = Total Cost / Number of shorts
∴ Unit Rate for Mart Y = $ 72 / 24 ....................... (As per given information)
∴ Unit Rate for Mart Y = $ 3 per short
Unit Rate for Mart Z = Total Cost / Number of shorts
∴ Unit Rate for Mart Z = $ 70 / 14 ....................... (As per given information)
∴ Unit Rate for Mart Z = $ 5 per short
From the above calculations, we observe that Unit price of Mart Y is the lowest ($ 3) among the 3 marts.
Hence, Best unit rate of purchase among all the three brands is Mart Y i.e. $ 3 per short.
Final Answer- 'Option A' i.e. 3.
