M manish

Here per cent implies for ( $\% \rightarrow \frac{1}{100}$ )

Therefore,
(a) 15% of 250
$15\times \frac{1}{100}\times 250 =\frac{75}{2}$
= 37.5

(b) 1 $\%$ of 1 hour
= 1 $\%$ of 60 minutes
$=\frac{1}{100}\times 60 =\frac{3}{5}\ min$
$=\frac{3}{5}\times 60 = 36\ sec$

(c) 20 $\%$ of Rs 2500
$=\frac{20}{100}\times 2500 =Rs\ 500$

(d) 75 $\%$ of 1 kg
We know that 1kg = 1000 gm, therefore,
$\frac{75}{100}\times 1000g=750g$
=0.75 kg
