Dont know how to solve this !!
Dear
Shrivathsan,
I'm happy to respond.
What is the source of this question? There are multiple problems with the question itself. The text contains a grammar mistake, the "
due to" mistake:
"...
due to the influx of refugees and the increasing population, the demand for bread has been increasing ... "
That would be wrong on GMAT SC.
Next, the prompt contains a crucial error:
...predicted that in 2016, the demand for bread will be, for the time time,
greater than the supply.
I assume they mean for the "
first time," but this makes the whole question garbled.
Typically, the numbers in the box would be in increasing order in a real GMAT problem.
Finally, something is funny about the answer provided.
Call the demand D and the supply S. In 2006, D = 180 and S = 540. The difference between them is 540 - 180 = 360. If the gap between them closed at exactly 36 per year, they would be equal in ten years, in 2016. The gap must close at slightly more than 36. What sum is slightly more than 36? Well, 15 + 25 is 40. The increase in D must be the larger one, so let's say D increase by 25 and S decreases by 15. In 2016, D = 180 + 250 = 430 and S = 540 - 150 = 390, so D > S in 2016. Check that this is the first time: in 2015, D = 430 - 25 = 405, and S = 390 + 15 = 405, so they would be equal. Thus, 2016 would be the first year in which D > S.
According to my calculations, we have to have:
D increase by 25
S decrease by 15
Those are answers of
[C] &
[J]. I don't agree at all with the answer posted.
I don't know what this source is, but if this problem is at all representative, I think you should set fire to the installation disc.
This is a poor question. Here's a set of six high quality 2PA questions:
