 \sf{let \: us \: find \: c.p \: at \: 25\% \: gain}

 \bf{c.p =  \frac{s.p \times 100}{(100 + gain\%)} }

\bf{ \underline{ \underline{proof : }}}

proof:

\sf{s.p \: = \: 12000}s.p=12000

\sf{let \: us \: find \: c.p \: at \: 25\% \: gain}letusfindc.pat25%gain

\bf{c.p = \frac{s.p \times 100}{(100 + gain\%)} }c.p= </p><p>(100+gain%)</p><p>s.p×100

\bf{ ⟹\frac{12000 \times 100}{100 + 25} }⟹ </p><p>100+25</p><p>12000×100

\bf{ \red{⟹9600}}⟹9600

\sf{let \: us \: find \: c.p \: 25\% \: loss}letusfindc.p25%loss

\bf{c.p = \frac{s.p \times 100}{(100 - loss\%)} }c.p= </p><p>(100−loss%)</p><p>s.p×100

\bf{ ⟹\frac{12000 \times 100}{100 - 25} }⟹ </p><p>100−25</p><p>12000×100

\bf{⟹ \frac{1200000}{75} }⟹ </p><p>75</p><p>1200000

\bf{ \red{⟹160000 }}⟹160000
