Question

what is the answer in step by step​

Answer 1

$Cost \: price \: of \: T.v = R.s \: 8000$

$profit \: on \: tv = cp × profit %$

$profit \: \: on \: tv \: = 8\% \: of \: 8000$

$= 8000 \times \frac{4}{100}$

$= 80 \times 8$

$= rs \: .640$

$Cost \: price \: of \: vcr = R.s \: 8000$

$loss \: on \: vcr = cp × loss %$

$loss \: \: on \: vcr \: = 8\% \: of \: 8000$

$= 8000 \times \frac{4}{100}$

$= 80 \times 4$

$= rs \: .320$

$Net \: profit = 640 - 320$

$= \: rs.320$

$Profit \: \% = \frac{profit}{cp} \times 100$

$Profit \: \% = \frac{320}{16000} \times 100$

$Profit \: \% \: = \frac{32}{16}$

$Profit \: \: \% = 2\%$
