A supermarket earns 5½% as discount on the total purchasing value and a bonus of ½% on sales more than Rs.10,000. What is the total sale value if it earns Rs.1,990?
Answer & explanation
Correct answer: option 3
Let total sales = 100x
Given :-
Discount = 5.5%
And bonus on sales more than 10000 = 0.5%
i.e. 0.5% on ( 100x - 10000 )
\(\frac{5.5}{100}\) × 100x + \(\frac{0.5}{100}\) (100x - 10000) = 1990
5.5x + 0.5x - 50 = 1990
6x = 2040
x = \(\frac{2040}{6}\)
x = 340
100x = 34000
So , total sales are 34000
