may be coz,i'd found myself understanding the problem:)

but really thanks a lot for your effort..

Another Q from geometry:

OA:5

P.S : Good Night,And Good Luck

I guessed this one would be option 5 because the answer would be 12+a*sqrt(b) :sneaky:
12 because AE + ED = 12, and the other side would be a*sqrt(80)

And only option5, has that form. But is there a better way to do this? Something conceptual?

1.312211
2.222211
3.311211

This is just counting the number of 1's and 2's.
3 times 1 then 2 times 2 then 1 time 1.
So, 312211.
