Hi I have a question I recently gave two gmat club tests. Scored a 42 and 43 on quant. Does anyone have any idea what this roughly translates to on the actual gmat quant?

I think it depends on person to person For me, for example, its been roughly the same. But on average, based on what I have read, a +2 on real Gmat compared to GmatClub

Easiest way to do this:
Set up equation as follows:
(10+2x)(100-5x)=1360
Where x represents each $2 increase.
Now test answers, starting with C since its middle.
Price is 16, so x=3
(10+2(3))(100-5(3))=1360, therefore C.

Target: Z=?

1) z is R when y/y-1, y is an int >0.
testing: y=2, 2/1, R0 (z=0), y=3, (3/2), R1, (z=1). Therefore, NS. We have two cases.
2) y is non-prime. no info about X, insuff.
3) since y is non-prime, we can exclude the case of y=2. Let’s test some more values:
y=6, 6/5, R1 (z=1)
y=8, 8/7, R1 (z=1)
y=9, 9/8, R1 (z=1)
Clear pattern here. Therefore, C.

Even multiples of 15 from 295 to 615 are 300, 330, 360 .... 570, 600
Total numbers = (600-300)/30 + 1 = 11
Sum = 11/2 (300+600) = 11/2 * 900 = 11*450 = 11*9*25*2 = 2*(3^2)*(5^2)*11
Hence, 11 is the greatest prime factor

if y = 2, then y/(y-1) has remainder as 0. rest all cases remainder is 1. combining both statement addresses this outlier, hence C

No, I don’t think so, it is just a marketing gimmick :lol: :lol: :lol:

Hopefully something catchier than Quant Chat but welcome ideas from more talented marketers. My skills tend to suck at 11 PM :lol:

the minute hand makes an angle of (24/60)*(360) = 144
Difference = 144-12 = 132

Statement 1: If units digit of 2m is 4, then the units digit of m can be either 2 or 7. Take 62, 2*62=124. Take 67, 2*67=134. Eliminate A and D.

Statement 2: If units digit of m equals to tens digit of 2m, then m can either be 62, 2*62=124 or 74, 2*74=148. Ofcourse these are just 2 such examples. Eliminate B.

Now, m is either of 52, 57, 62, 67, 72, 77, 82, 87, 92, and 97. Of these when you do 2m, you get 104, 114, 124, 134, 144, 154, 164, 174, 184, and 194. We see that 62 and 87 meet both the conditions, hence answer is E.
