In a meeting," $\frac{4}{25}$ of the members were female. What percent of the members was this?

16%

Let the total number of members in meeting = $x$
Then, the total number of females in meeting= $\frac{4 x}{25}$

Required percentage = $\frac{N u m b e r o f f e m a l e s}{T o t a l n u m b e r o f m e m b e r s} \times 100$

$\Rightarrow \frac{\frac{4 x}{25}}{x} \times 100 % = 16$

A shop reduced its prices by 10%. What is the new price of an item which was previously sold for $₹$ 500?

$₹$ 550
$₹$ 450
$₹$ 400
$₹$ 510

$₹$ 450

Given, the original price of an item= $₹ 500$

and reduced percentage = $10 %$

$∴$ New price item= $o r i g i n a l p r i c e \times \frac{(100 - r e d u c e d p e r c e n t a g e)}{100}$

= $500 \times \frac{(100 - 10}{100}$

= $500 \times \frac{90}{100}$ = $₹ 450$
