Question

When a no is increased
by 1/20 it becomes 111 1/9% of itself what is the number ?​

Answer 1

Answer:

The number is $\frac{9}{20}$.

Step-by-step explanation:

Let the number be x.

It is provided that:

$x+\frac{1}{20}=111\frac{1}{9}\%\times x$

Solve for x as follows:

$x+\frac{1}{20}=\frac{1000}{900}\times x\\\frac{10}{9}x-x=\frac{1}{20}\\\frac{10x-9x}{9}=\frac{1}{20}\\x=\frac{9}{20}$

Thus, the number is $\frac{9}{20}$.
