Answer 1

Answer:

$cp \: of \: the \: radio \: = 860 \: ans$

Step-by-step explanation:

$sp \: of \: the \: radio \: = 903$

$gain\% = 5\%$

$cp \: of \: the \: radio \: = \frac{sp \times 100}{(100 + gain \%)}$

$\frac{903 \times 100}{(100 + 5)}$

$\frac{903 \times 100}{105}$

$\frac{903 \times 20}{21}$

$\frac{18060}{21}$

$860$
