A manufacturer of a certain product can expect that between 0.3 percent and 0.5 percent of the units manufactured will be defective. If the retail price is $2,500 per unit and the manufacturer offers a full refund for defective units, how much money can the manufacturer expect to need to cover the refunds on 20,000 units? (A) Between$15,000 and $25,000 (B) Between$30,000 and $50,000 (C) Between$60,000 and $100,000 (D) Between$150,000 and $250,000 (E) Between$300,000 and $500,000 Kudos for a correct solution. _________________ Verbal Forum Moderator Status: Greatness begins beyond your comfort zone Joined: 08 Dec 2013 Posts: 2291 Location: India Concentration: General Management, Strategy Schools: Kelley '20, ISB '19 GPA: 3.2 WE: Information Technology (Consulting) Re: A manufacturer of a certain product can expect that between 0.3 percen [#permalink] ### Show Tags 14 Oct 2015, 21:56 3 1 Number of defective units is between = .3 % of 20000 and .5% of 20000 = 60 and 100 Retail Price per unit = 2500$
Expected price of refund is between = 2500 x 60 and 2500 x 100
=1,50,000 and 2,50,000 dollars

since 200,000 fits in the $150,000 and$250,000 range.

0.3 percent is 3 per thousand. 3 per thousand of 20 thousand is 3 x 20 = 60.

Lower bound for total price of defective units: 60 x 2.5 thousand = 150 thousand.

Thus D is the correct answer choice.

If you look at the answer format, you can easily notice that all maximum values are different (also calculating 0.5% will cancel out easier than 0.3%)

Thus maximum refund to expect = 0.5% x 2,500 x 20,000 = 250,000

Hint: 0.5% x 20,000 x 2500 = 0.5 x 20000 x 2500/100 = 10,000 x 25 = 250,000

How much money need to cover for refund ?
Number of units = 20,000 units
cost = 2500$/ unit 0.3% of units = 3/1000 x 20,000 = 60 units defective 0.5% of units = 5/1000 x 20,000 = 100 units defective Between 60x2500$ = 150,000$100x2500$ = 250,000$D _________________ I welcome analysis on my posts and kudo +1 if helpful.

(A) Between $15,000 and$25,000
(B) Between $30,000 and$50,000
(C) Between $60,000 and$100,000
(D) Between $150,000 and$250,000
(E) Between $300,000 and$500,000

If at least 0.3 percent of the 20,000 units are defective, then at least 0.3/100 x 20,000 = 60 units will be defective costing 60 x 2,500 = 150,000 dollars.

Since we see that 150,000 is the “low” number and only answer choice D has 150,000 as the low number, answer choice D must be correct.

Kudos for a correct solution.

ok here is a quick method

remove all zeros 2,500 = 25
and 20,000 = 2

total number of units 25*2 = 50

now add remaining number of zeros ( add six zeros) 50, 000, 000

5*3 = 15 and 5*5 = 25
