\(=\frac{50.2*0.49}{199.8}=\frac{(50)(50)x10^{-2}}{200}=\frac{2500*10^{-2}}{200}=125*10^{-3}=\frac{125}{1000}=\frac{1}{8}\)

Answer: B

Of the following, which is the closest approximation of 50.2*0.49/199.8
\(\frac{50 * .5}{200} = \frac{25}{200} = \frac{1}{8}\)

IMO B

50.2 ~ 50 ; 0.49 ~ 0.50 = 1/2 & 199.8 ~ 200

So, We have \(50*\frac{1}{2}/200 = 25/200 = 1/8\) , Answer must be (B)
