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

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.

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.

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.

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.

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.

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

a) 1

c) 3
d) 4
e) 5

B(1), G(5), P(x), R(11)
5<x<11

Prime factors of 88 000: 2,2,2,2,2,2,5,5,5,11
x=8
---> 2 purple chips.

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

a) 1
b) 2
c) 3

e) 5

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.

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.

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

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?
