    C)         \[33\frac{1}{3}\]                

    D)         40

    Correct Answer: C

    Solution :

    Let the number is x. According to question \[x-10%\]of \[x=30\] \[x-\frac{10}{100}x=30\] \[\left( \frac{100-10}{100} \right)x=30\] \[x=\frac{30\times 100}{90}=33\frac{1}{3}\] Hence, the number is \[33\frac{1}{3}\]
