Answer 1

SOLUTION :

GIVEN

Sunita's income is 10% less than that of Anita

TO DETERMINE

The percentage of Anita's income more than that of Sunita

CALCULATION

Let the income of Anita = P

Now it is given that Sunita's income is 10% less than that of Anita

So the income of Sunita

$\displaystyle \sf{ = } \: P \times \frac{90}{100} = \frac{9P \: }{10}$

So the amount of Anita's income more than that of Sunita

$\displaystyle \sf{ = } \: P - \frac{9P \: }{10} = \frac{P \: }{10}$

So the percentage of Anita's income more than that of Sunita

$\displaystyle \sf{ = \frac{ \frac{P \: }{10} }{ \frac{9P \: }{10}} } \times 100 \%$

$\displaystyle \sf{ = \frac{1}{9} } \times 100 \%$

$\displaystyle \sf{ = } \: \: 11 \frac{1}{9} \: \%$
