I have one stupid question about divisibility and remainder and it really confuses me. I'll much appreciate your explanation. About divisibility: It's clear that 10 is indivisible by 3 and the remainder is 1 (because 1/3 is infinitive) However: Is 12 divisible by 8 as the result is 1.5 (4 is divide...

If n is a positive integer and r is the remainder when n^2-1 is divided by 8, what is the value of r? 1)n is odd 2)n is not divisible by 8 You might notice that this is a difference of squares: n^2 - 1 = (n+1)(n-1) If n is odd, then n-1 and n+1 are consecutive even integers. If you take any two con...

champmag wrote:What is the value of y?

(1) 3|x^2 – 4| = y – 2

(2) |3 – y| = 11

OA after some discussion.
IMO: C
(1) tells us: y-2>0 -> y>2 => Insufficient
(2) tells us y = -8 or 14 => Insufficient
Combine
-> y=14 => sufficient
Thanks

shebinjs wrote:If -2x > 3y, is x negative?
1) y > 0
2) 2x + 5y - 20 = 0

How to analyse statement 2 for data sufficiency?

Thanks
IMO : A
1. it's clear that 3y > 0, in order that -2x > 0 => x < 0
=> SUFFICIENT
2. 2x + 5y = 20
if y > 4, x <0
if y < 4, x > 0
=> INSUFFICIENT

LOL, how crazy I was !!!!!! I picked option B, coz in (1) y + 8 is a factor of y2 + ay - 24, I almost forgot that y2 + ay - 24 = 0, So I just kept in my mind a statement that y2 + ay - 24 is divisible by (y + 8) and totally ignored that y2 + ay - 24 = 0 Let's try this problem guys, a tougher one.
