A sporting goods store received a shipment of baseball gloves that included 5 brown gloves for every 6 black gloves. Did the store receive at least 250 gloves in the shipment?

Given: Black:Brown=6x:5x, so the # of black gloves is a multiple of 6 and # of brown gloves is a multiple of 5.

(1) 44% of the left-handed gloves in the shipment were black --> 44%=11/25 of left-handed gloves are black, thus the # of left-handed gloves is a multiple of 25. Not sufficient.

(2) The shipment included 84 black, right-handed gloves. Also not sufficient.

(1)+(2) We have the following matrix:

Notice that we have that 84+\frac{11Y}{25}=6X.

Now, since both 84 and 6x are multiples of 6, then \frac{11Y}{25} must also be a multiple of 6, which means that Y must be both multiple of 25 and 6, or a multiple of 150 (LCM of 25 and 6). Thus the least value of Y is 150. In this case 84+\frac{11*150}{25}=150=6x --> X_{min}=25 --> Total=6X+5X=11x=275>250. Sufficient.

That's not correct.

First of all, we cannot get the exact number of the gloves in the shipment. Next, the # of gloves MUST be a multiple of 11, so the # of gloves cannot be 258.

Bunuel,I feel this question is a bit out of place for GMAT, ONLY because it requires one to know that baseball glvoes don't come in pairs.Your take?

Yes, in baseball players wear only one glove, but not sure that this is a common knowledge, thus real GMAT question would probably make note about that.

I just went through the complete thread...I didn't have any clue about baseball stuff.. So there cant be 5 brown and 6 black gloves..as they have to be in pairs(My assumption)..Hence I deduced the 10 -12 logic Same assumption for 2nd statement and you should get a D.. Not a GMAT type question..No body outside US follows baseball(I believe)

Hi Bunuel,

please correct me ....

A is not sufficient since we don't know the exact number of the total left hand gloves.

for B if we know there are 84 right hand gloves, then there will be equivalent number of left hand side gloves. hence the total will be 168. Also, its given the ration of Brown to black 5:6 ... hence 140 another gloves .... this makes the total more than 250 .. sufficient .

For me answer should be B ... Can you please help me to understand this.
