    In an examination, a student was asked to find \[{{\frac{3}{14}}^{th}}\] of a certain number. By mistake, he found \[\frac{3}{4}\] of it. His answer was 150 more than the correct answer. What was the number given to him?

    A)  \[290\]                                

    B)                         \[280\]                

    C)                         \[240\]                                

    D)                         \[180\]                

    Correct Answer: B

    Solution :

    Let the required number be 'x?. Then,  \[\frac{3x}{4}-\frac{3x}{14}=150\] \[\Rightarrow \] \[x=\frac{150\times 28}{15}=280\]
