    C)  60.5                            

    D)  121

    Correct Answer: A

    Solution :

    (a): \[\frac{3}{2}\times \frac{4}{3}\times \frac{5}{4}\times \frac{6}{5}.........\times \frac{200}{199}\times \frac{201}{200}\] \[\frac{3}{2}\times \frac{4}{3}\times \frac{5}{4}\times \frac{6}{5}.........\times \frac{200}{199}\times \frac{201}{200}\] \[\frac{201}{2}=100.5\]
