1) Solving the inequality gives us \(x \in (1;0) u (0;1)\).
Option 1 and Option 2 include both the solutions and nonsolutions, making them insufficient. Combination of (1) and (2) give us the exact interval, where the inequality holds.
C it is.

http://mathrevolution.com/gmat/daily_quiz My approach got me the answers as "either statement alone" i.e. "D" From stat 1) n/8 = ax+3, implying n = 8ax + 24, implying n/6 = 3/2 (ax) + 4, 3/2 (ax) shall always give 1 as remainder therefore total remainder = 5...Suff. From stat 2) (n1)/9 = ax+8, implies n1 = 9ax + 72, implies (n1)/6 = 3/2(ax) + 12, 3/2 (ax) shall always give 1 as remainder whereas 12 is divisible terefore remiander = 1...suff Therefore "D" where did I go wrong:(

saurabhsavant Hello, In fact, "n/8 = ax+3,(n1)/9 = ax+8" is incorrect. It is supposed to be shown as "n=8p+3 and n1=9q+8".

It doesn't mean that its remainder is 3 when n is divided by 8, but it means n is multiple of 8. It should be expressed by n = 8a + 3 Condition 2) You shouldn't write (n1)/9 = ax + 8. It means n  1 = 9 * ( ax + 8 ) and the remainder of n  1 is 0 when n  1 is divided by 9 It should be expressed by n  1 = 9b + 8 Happy Studying! Math Revolution
