Question

Which store has a better deal on football if store $ A $ sells footballs for Rs. and sto $ 4 $ re $ B $ sells \[5\] footballs for Rs. $ 4 $ ?
A.Store $ A $ has a better deal than $ B $ .
B.Store $ B $ has a better deal than $ A $ .
C.Both stores have the same deal.
D.Cannot be determined.

Answer 1

Hint: In order to find the solution of these kinds of questions, first we need to find the price of $ 1 $ football from each store with the help of a unitary method. Then, compare both prices. The store having a lesser price per football deal would be better.

Complete step by step solution:
Deal of store $ A = $ $ 4 $ footballs for Rs. $ 3 $ .
Deal of store $ B = $ $ 5 $ footballs for Rs. $ 4 $
For store $ A $ the price of $ 1 $ football $ = \dfrac{{{\text{Total number of footballs}}}}{{total{\text{ }}price}} $
 $ = \dfrac{4}{3} $
 $ = 1.33 $
For store $ B $ the price of $ 1 $ football $ = \dfrac{{{\text{Total number of footballs}}}}{{total{\text{ }}price}} $
  $ = \dfrac{5}{4} $
 $ = 1.25 $
Hence by comparing the both prices we will get that that store $ B $ price of $ 1 $ football is lesser than that of store $ A $ .
So, The deal of the store is $ B $ better.
Final answer: The Store $ B $ has a better deal than $ A $ . So, option B. is the correct answer.
So, the correct answer is “Option B”.

Note: Some points to be kept on mind will solving these kinds problems:
You should always compare the price after finding the price of a $ 1 $ object.
This question is more of a test for a sense of humor than Mathematics. So, always be attentive.
The unitary method should be used properly.
