Question

please answer my ques with solution ​

Answer 1

Given,

My salary is 50% less than my brother's salary.

Solution,

Consider my salary is x and my brother's salary is y.

$\[\begin{array}{l}x = y - 50\% y\\ \Rightarrow x = y - \frac{{50}}{{100}}y\\ \Rightarrow x = y - \frac{1}{2}y\\ \Rightarrow x = \frac{1}{2}y\end{array}\]$

Calculate the percentage of my brother's salary more than mine.

$\[y = 2x\]$

$\[ \Rightarrow y = x + x\]$

$\[ \Rightarrow y = x + 100\% x\]$

Hence my brother's salary is $\[100\% \]$ more than mine salary.

Answer 2

Answer:

let my brother's salary = 100

my salary = 100- 50%of 100

= 100-50/100 * 100

= 100- 50

= 50

The percent from which my brother salary is more than mine

= [100-50/50 * 100] %

= 50/50*100

=100
