    0.1 and \[\frac{5}{8}\] of a bamboo are in mud and water respectively and the rest of length 2.75 m is above water. What is the length of the bamboo?

    A) 10 m

    B)  30 m

    C)  27.5 m

    D)  20 m

    Correct Answer: A

    Solution :

    Let the length of bamboo be x m. \[\therefore \]Length of bamboo above water \[=x-\frac{x}{10}-\frac{5x}{8}\] \[=\frac{40x-4x-25x}{40}=\frac{11x}{40}\] According to the question, \[\frac{11x}{40}=2.75\] \[\Rightarrow \]   \[x=\frac{2.75\times 40}{11}=10\,\,\text{m}\]
