Answer 1

The Correct Option is C

Let the price of the car which Arun and Rakesh bought be 'x'
A) Arun got 10\(\%\) discount from the dealer after which 7% sales tax was added, 
Effective price of the car = 90\(\%\) of 93\(\%\) of x 
B) For Rakesh 7\(\%\) tax was added and only then a 10% discount was given, 
Effective price of the car = 93\(\%\) of 90\(\%\) of x 
Both the quantities are equal. 
Hence, option C is the correct answer.The correct option is (C): If quantities A and B are equal
