Given :-

$\\ \\$

To find:-

$\\ \\$

First let's find increase in price :-

$\\$

$\boxed{ \rm increase\% = (increase)/(original \: price) * 100 }$

$\\ \\$

So:-

$\\$

$\dashrightarrow \rm increase\% = \sf (increase)/(original \: price) * 100 \\$

$\\ \\$

$\dashrightarrow \rm increase\% = \sf (6)/(30) * 100 \\$

$\\ \\$

$\dashrightarrow \rm increase\% = \sf (6)/(3\cancel0) * 10\cancel0 \\$

$\\ \\$

$\dashrightarrow \rm increase\% = \sf (6)/(3) * 10 \\$

$\\ \\$

$\dashrightarrow \rm increase\% = \sf \cancel(6)/(3) * 10 \\$

$\\ \\$

$\dashrightarrow \rm increase\% = \sf 2* 10 \\$

$\\ \\$

$\dashrightarrow \bf increase\% = 20\%$
