This is a tricky one. They are trying to get us to quickly pass DS item #2 since there are two variables.
I came to 'B' by looking at the units digits of .23 and .21, and multiplying them till the sum of the two products was divisible by 10.
Units digit of .23 is 3. Units digit of .21 is 1. 3x2=6; 1x4=4. 6+4=10.
Now plug into the equation: .23(2)+.21(4)=.46+.84=1.30.
I admit that I used DS item #1 to speed things up, but I worked assuming that a person that is stronger in math would have found a way to get there without "cheating", so I assumed '2' must be sufficient in all cases. Maybe an expert can weigh in, but I agree that the answer is B.
I don't know what to say, really. Three minutes to the biggest battle of our professional lives. You find out life's this game of inches, so is football. Because in either game - life or football - the margin for error is so small. I mean, one half a step too late or too early and you don't quite make it. One half second too slow, too fast and you don't quite catch it. I'll tell you this, in any fight it's the guy whose willing to die whose gonna win that inch. That's football guys, that's all it is. Now, what are you gonna do?
