    The diameter of a wheel is 98 cm. The number of revolutions in which it will have to cover a distance of 1540 m is

    A) 500

    B) 600

    C) 700

    D) 800

    Correct Answer: A

    Solution :

    [a] \[\because \]\[d=98\,cm\] \[\therefore \]Circumference of wheel \[=\pi \,d\] \[=\frac{22}{7}\times 98=308\,cm\] Hence, number of revolutions \[=\frac{\text{Distance}}{\text{Cicumference}\,\text{of}\,\text{wheel}}\] \[=\frac{1540\times 100}{308}=500\]
