A salesman sold vacuum cleaners with a special 30-day, money-back guarantee. He sold a total of T vacuum cleaners at a price of D each. Q of the vacuum cleaners were returned within 30 days, and the salesman returned the money to those people. Which of the following expressions represents the money the salesman got from actual sales (people that kept their vacuum cleaners) as a percentage of the total amount of money that he made before having to make refunds?
(A) \(100\% × \frac{TD}{QD}\)
(B) \(100\% - Q/TD\)
(C) \(\frac{(100\% - (100QD))}{TD}\)
(D) \(\frac{100\%(TD - QD)}{TD}\)
(E) \(100\%(TD - QD)\)
(A) \(100\% × \frac{TD}{QD}\)
(B) \(100\% - Q/TD\)
(C) \(\frac{(100\% - (100QD))}{TD}\)
(D) \(\frac{100\%(TD - QD)}{TD}\)
(E) \(100\%(TD - QD)\)

Initial sales= TD
Returned Q
Final sales = (T-Q)*D= TD-QD
TD*(x/100)= TD-QD
x= 100(TD-QD)/TD

(D) \(\frac{100\%(TD - QD)}{TD}\)
(E) \(100\%(TD - QD)\)
Total sold = T at D$ each
--> Total amount = T*D
Q cleaners have been returned
--> Net Sold = T - Q
--> Total amount remaining = (T - Q)D
% of actual sales = (T - Q)D/TD*100
= 100(TD - QD)/TD
IMO Option D
