• # question_answer A number when reduced by 10% gives 30. The number is A)  35                    B)  33$\frac{1}{2}$ C)  33$\frac{1}{3}$           D)  40

[c] 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 $33\frac{1}{3}$
