Answer 2

$\huge \pink{ \boxed{ \boxed{ \mathfrak{solution}}}}$

cp=250×8

=₹2000(actual cp)

$\blue{70\% \: of \: 250}$

$\pink{ \frac{70}{100} \times 250}$

$\blue{7 \times 25}$

$\pink{ = 175}$

$\blue {sp \: of \: 175 \: packets = 175 \times 11}$

$\pink{ = 1925}$

$\blue \therefore \blue{30\%of \: 250 = 250 - 175}$

$\pink{ = 75}$

$\blue{sp \: of \: 75 \: packets = 75 \times 9}$

$\pink{ = 675}$

$\huge \green{ \underline{ \underline{now}}}$

$\blue{total \: sp = 1925 + 675}$

$\pink { = 2600(actual \: sp)}$

$\orange{ \boxed{profit = sp - cp}}$

$\blue{2600 - 2000}$

$\pink{ = 600}$

$\red{ \boxed{profit\% = \frac{profit}{cp} \times 100}}$

$\blue \implies{profit\% = \frac{600}{2000} \times 100}$

$\implies \: profit\% = 30\%$
