Man's wages

Let the initial wage is 100.After an increase of 10% , the salary becomes 110. After a decrease of 10% from 110,we get 99,which indicates that there is a loss of 1%.

After the 10% increased, it became $x+0.1x=1.1x$ .

After the 10% decreased, it became $1.1x-0.1(1.1x)=0.99x$

Total decreased therefore is $x-0.99x=0.1$ or $1\%$ .

Hello & peace be upon you,

let x = wages,

10% increment = (0.1x + x ) = 1.1x,

then, 10% decrement = 1.1x - [(0.1)(1.1x)] = 0.99x,

total decrement = (x - 0.99x) = 0.01x

total decrement(%) = 0.01x/x . 100% = 1%

thanks...
