    Observe the given figure in which the heights of two poles \[P\] and \[Q\] are given. If the height of pole \[P\] is\[225\,\,cm\], how much shorter than \[3\,\,m\] is pole\[Q\]?

    A) \[180\,\,cm\]                  

    B)                    \[120\,\,cm\]                  

    C)                    \[140\,\,cm\]                  

    D)                    \[160\,\,cm\]                  

    Correct Answer: B

    Solution :

    From the figure, the 5th mark denotes the height of pole \[P\] which is\[225\,\,cm\]. So, each marking is at\[\frac{225}{5}cm=45\,\,cm\] Pole \[Q\] is at the 4th mark. So, the height of pole \[Q=4\times 45\,\,cm=180\,\,cm\] The difference\[=3\,\,m-180\,\,cm\] \[=(300-180)cm=120\,\,cm\] So, pole \[Q\] is \[120\,\,cm\] less than\[3\,\,m\].
