If | r - 6 | = 11 and | 2q - 12 | = 8, what is the minimum possible value of q / r?
-2/5
2/17
10/17
None of these
| r-6 | = 11 => r = -5 or 17
| 2q - 12 | = 8 => q = 10 or 2
So, the minimum possible value of q/r = 10/(-5) = -2

Why not q = 2 for minimum value? .................................................................................................
Hi,
Case 1: If q=2, r=-5 q/r = -0.4
Case 2: q=2, r= 17 q/r= 0.1
Case 3: q=10, r=-5 q/r = -2
Case 4: q=10, r=17 q/r = 0.58
Out of 4, case 3 gives the least value.
Hope this helps.
