    The simplification of \[\left( 1-\frac{1}{2} \right)\left( 1-\frac{1}{3} \right)\left( 1-\frac{1}{4} \right)...\left( 1-\frac{1}{100} \right)\]results in

    A)  0.01    

    B)  0.001

    C)  1

    D)  0.1

    Correct Answer: A

    Solution :

    \[\left( 1-\frac{1}{2} \right)\left( 1-\frac{1}{3} \right)\left( 1-\frac{1}{4} \right)...\left( 1-\frac{1}{100} \right)\] \[=\frac{1}{2}\times \frac{2}{3}\times \frac{3}{4}\times ...\times \frac{9}{100}=\frac{1}{100}=0.01\]
