    32% of a number exceeds 17% of the same number by 120. What is the value of the number?

    A)  900     

    B)         860

    C)  940                 

    D)  800

    Correct Answer: D

    Solution :

    [d] Required number \[\Rightarrow \,\,\,\frac{x\times 32}{100}-\,\frac{x\times 17}{100}=120\] \[\Rightarrow \,\,\,\frac{32x-\,17x}{100}=120\] \[\Rightarrow \,\,\,\frac{15x}{100}=120\] \[\therefore x=\frac{120\times 100}{15}=800\]
