https://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) (n-1)/9 = ax+8, implies n-1 = 9ax + 72, implies (n-1)/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:(
