    Direction: The pie-chart shows the number of vehicles in a car park. The total number of vehicles in the car park is\[\mathbf{7000}\]. \[\mathbf{AB}\] is the diameter. If \[30%\] of the 'Others' are cycles, how many cycles are there?

    A) \[117\]                          

    B)                    \[28\]                

    C)                    \[147\]                          

    D)                    \[49\]                

    Correct Answer: C

    Solution :

    The fraction representing the 'Others' in the pie-chart             \[=1-\left( \frac{1}{4}+\frac{19}{50}+\frac{3}{25}+\frac{9}{50} \right)=\frac{7}{100}\] Given \[30%\] of the 'Others' are cycles, the number of cycles \[=30%\] of \[\frac{7}{100}\] of \[7000\]\[=\frac{30}{100}\times \frac{7}{100}\times 7000=147\]
