Nice explanation byGMATinsight . My explanation is bit similar.
Most probably you get\((a+b)^2\) or\((a+b)^2-c^2\) = (a+b+c)(a+b-c) in such questions.
Or there is a direct observation- 2200= 22*100 = 22*(2*2*25) = 44*2*25
nick1816 Could you please explain how you have caught the tricky PS above is a reflection of aformula?
