Is there any other way apart from doing tedious-math?

Approximate.

1/.03 = 100/3 = 33
1/.37 = 100/37 = 3
Denominator becomes 33 + 3 = 36

1/36 = .02something

$$\frac{1}{(1/0.03+1/0.37)}$$

$$\frac{1}{((0.37+0.03)/(0.03 * 0.37))}$$

$$\frac{(0.03 * 0.37)}{0.40}$$

Here we see that 0.37 ≈ 0.40
Just consider 0.37/0.40 Denominator is slightly greater than Numerator so the answer is close to 0.03 is less than 0.03.
From the answer choices we see that 0.02775 matches our required value.

Project PS Butler : Question #107

By inspection Denominator > 1 , So Choices C, D, and E are ruled out

Also, if Choice A were the answer, denominator would be (1/0.004) = 250, Which is not the case ( By Inspection)

So, Choice B remains
