PR CAT 1
In a sequence of 13 consecutive integers, all of which are less than 100, there are exactly 3 multiples of 6. How many integers in the sequence are prime? (1) Both of the multiples of 5 in the sequence are also multiples of either 2 or 3. (2) Only one of the two multiples of 7 in the sequence is not...

Unable to access PR online tests
Hi All I purchased the "Cracking the GMAT, 2008 Edition" from Princeton. The book says i can access 4 online tests on the Princeton's website. I have registered the book by putting in the serial number and also registered myself on the website. I am only able to see two links on the PR web...

If q is Odd...then q^4 will be odd. So (q^4/64) and (q^4/128) can never be integers. No specific conclusion from this. If q is Even. (q^4/128) = (q^4/64) * (1/2). The only way (q^4/128) can be an integer is IF (q^4/64) is an even integer. I am unable to find a case where (q^4/64) is an odd integer. ...

Let Angle QRS be equal to Y. From Stmt 1, Angle SQR is equal to Y. So Angle PRT = (180 - 2*Y)
Let Angle UST = Z. From Stmt 2, Angle SUT = Z. So Angle UTS = (180 - 2*Z).
Sum of angles in a traingle is 180. So (180-2*Y) + (180-2*Z) + 90 = 180.
Y+Z = 135. But X+Y+Z = 180. So X = 45.

In Continuation to what AleksandraM did... 11y = 19z. In this equation both y and z are quotients. So they are integers. z = 11y/19. If z has to be an integer, then it must be that y is divisble by 19. If y is not divisible by 19, there is no way 11y/19 would become an integer. Since y has to be div...
