a) 1
b) 2
c) 3
d) 4
e) 5


\(88,000=2^6*5^3*11\), as no chip's value is multiple of 2, hence 2^6=64 must be the product of the values of the purple chips drawn. The value of the purple chip is multiple of 2, but more than 5 and less than 11, hence it's 8 (2^3). 8*8=64, two purple chips were drawn.

Answer: B (2).

Break it down into LCFs:
88000 --> 1000 * 88 --> 5*5*5*2*2*2*11**2*2*2
So, possible chips:
3 green (5 points)
1 red (11 points)
who cares about blue, because they are worth one.
leaving 2*2*2*2*2*2 for the purple.

We know that purple is between 5 and 11, so 2^y must be 8, y=3
2*2*2*2*2*2=8*8
So, two purple.

The answer is B.

seems this question is a bit ambiguous, you could just draw all chips worth 5 and it'd divide up fine. It never said anything about having a random smattering of chips.

Answer: B (2).



to satisfy highlighted statement dont you think answer should be 8? which is not there, so i am totally bummed out! :cry:


Read the question again. It doesn't say "What is the value of the purple chip?" It says, "How many purple chips were selected?"
Since we have 2^6 and as you rightly figured that each purple chip has value 8 (= 2^3), there must have been 2 purple chips.

It isn't ambiguous.
You cannot draw all 5s because then you cannot have 88000 as the product. To make 88000, you need some 2s and 11 as well.

After looking at factors we can say that purple ball comes from 2^6.
now check the posibility because it mentioned that purple chips are worth more than the green chips, but less than the red chips ( 5 < Purple ball < 11), Thus the possible combinations are:
(2^1)^6 = 2^6 (5<x<11 not satisfied as x = 2)
(2^6)^1 = 64^1 (5<x<11 not satisfied as x = 64)
(2^2)^3 = 4^3 (5<x<11 not satisfied as x = 4)
(2^3)^2 = 8^2 ( satisfied condition)
Ans. 2

88000 = 2^6 * 5^3 * 11

5<x<11 => x could be 6 or 7 or 8 or 9 or 10

x cannot be 6 , otherwise we would have got a 3 in the product
x cannot be 7, otherwise we would have seen atleast one 7.
x cannot be 9 , otherwise we would have seen a 3 in the product
x cannot be 10 , otherwise we would have seen a 5 in the product.

=> x is 8

Also 2^6 in the product cannot be from R,G,B as none of them has 2 in it.

=> 8^n = 2^6
=> there are 2 purple chips

Answer is B

used a diff method.. but yea ans is B

88000/ 11 = 8000 (1 red chip)

8000/5 = 1600 ( 1 green chip)

1600 / 5 = 320 ( another green chip)

320 / 5 = 64 (another green chip)

since purple can be between 5 and 11, the apt number is 8 => 2 purple chips

Given:
B = 1
G = 5
P = x
R = 11
x > 5

\(88,000 = 2*2*2*11*5*2*5*2*5*2 = 2^6*11*5^3\)

WE know x is greater than 5 so it cannot be 2 nor 4. Then, it's 8. 16 is also not possible because we have to evenly divide the number of 2s.

Answer: B

The purple chips are worth more than the green chips, but less than the red chips.

Dont you guys think above statement should have been written as following:
The purple chip is worth more than the green chip, but less than the red chip.

Chips is referring to combined worth of all purple chips in the bag, a worth that is not helping any way to judge that single purple chip's worth is between Green's and Red's worth.

Hi All,

This question involves a bit of logical thinking and factoring skills. You have to take notes and stay organized though, if you want to answer this question correctly.

We're told:
Blue chips = 1 point each
Green chips = 5 points each
Purple chips = X points each (more than Green, less than Red, so X = 6, 7, 8, 9 or 10)
Red chips = 11 points each

We're told that taking an unknown number of chips gives us a product equal to 88,000; we need to factor 88,000 and we should look specifically for 5s, 11s and some mystery number between 6 and 10, inclusive….

88,000 =
(11)(8,000) =
(11)(5)(1600) =
(11)(5)(5)(320) =
(11)(5)(5)(5)(64)

Now, we KNOW that there's a mystery number that is between 6 and 10 (inclusive) and MUST account for that 64….

64 = (8)(8)

This gives us 2 purple chips.

Final Answer:

A. 1
B. 2
C. 3
D. 4
E. 5


5<x<11
x can be 6, 7, 8, 9, or 10.

88,000 = 88 * 1000 = 2*44 * 10^3 = 2*2*2*11 * 2^3 * 5^3
regroup:
2^6 * 5^3 * 11
6, 7, and 9 are right away out.
since we have 6 factors of 2 and only 3 factors of 5, it must be true that x can't be 10, even if we have 10 purple chips, and 0 green chips, we still have 3 factors of 2 that we can't cover anywhere..
10 is out.

remains only 8. so x must be 8, and we have two purple chips selected.

I had the same understanding and messed up the question. But what do the experts think is the question 100% correct or a little ambiguous?

Hi gauravk,

Can you go into more detail about how 'your interpretation' impacted the work that you did? After working through the question, what answer did you end up selecting?

On Test Day, you might inadvertently mis-understand what a Quant question states (it won't happen very often, but it is possible). However, in most of those cases, the answer that you end up with will NOT be among the 5 choices. THAT outcome proves that something about your interpretation was incorrect, so you can go back, review your work and think about how else you could have interpreted the information. This is one of the reasons why it's so important to write everything down on the pad; if you have to go back, then you have work that you can look at.

X can be 6,7,8,9,or 10

so factor 88,000 down into primes you get
11 once
2 6 times
5 three times

so that means X has to be a multiple of 12 (2*6). 6 is the only option

If the product of the point values of the selected chips is 88,000, how many purple chips were selected?

A. 1
B. 2
C. 3
D. 4
E. 5



88,000 = 88 x 1000 = 11 x 8 x 10 x 100 = 11 x 2^3 x 5 x 2 x 5^2 x 2^2 = 2^6 x 5^3 x 11^1

We see that there could be any number of blue chips since they are worth 1 point each. The prime factor 5^3 tells us that the number of green chips must be 3 since they are worth 5 points each. The prime factor 11^1 indicates that the number of red chips must be 1 since each red chip is worth 11 points. Thus, the product of the point values of purple chips must be 2^6. Since each purple chip is worth between 5 and 11 points, and the value of a purple chip must be a power of 2, each purple chip must be worth 2^3 = 8 points, since 8 is the only power of 2 between 5 and 11. Since 2^6 = 8^2, there must be 2 purple chips.

Answer: B

Since 2^6 = 8^2, there must be 2 purple chips.

Answer: B


ScottTargetTestPrep & Bunuel

What if I say that 11 indicates 1 Red while 5^2 indicates ONLY 2 Greens. In this case, I'll end up having 5 x 2^6. I will say that Purple worth 10, so I'll have one purple & the remaining will be Blues. So Answer will be A. What's wrong in my approach?
