Answer 2

$Given \: selling \:price (s.p) = Rs\:729$

$Loss (l) = 10\%$

$\red{ Find \: cost \:price (c.p) = ? }$

$We \: know \: that,$

$\boxed{\pink{c.p = \frac{s.p \times 100}{(100-l)} }}$

$c.p = \frac{ 729 \times 100}{(100-10)}$

$= \frac{ 72900}{90}$

$= Rs\:810$

Therefore.,

$\red{ Required \:cost\:price } \green { = Rs\:810}$
