$\sf{\red{\boxed{\bold{Gain= SP - CP}}}}$

⠀⠀⠀⠀

⠀⠀⠀⠀

$\sf : \implies\:{\bold{ Gain = Rs. 140 - Rs. 125 }}$

⠀⠀⠀⠀

$\sf : \implies\:{\bold{ Gain = Rs. 15 }}$

⠀⠀⠀⠀

⠀⠀

$\sf{\red{\boxed{\bold{Gain\% = \dfrac{Gain}{CP} \times 100}}}}$

⠀⠀⠀⠀

⠀⠀

$\sf : \implies\:{\bold{ Gain\% = \dfrac{15 }{125} \times 100 }}$

⠀⠀⠀

⠀⠀⠀⠀

$\sf : \implies\:{\bold{ Gain\% = \dfrac{3 }{25} \times 100 }}$

⠀⠀⠀⠀

⠀⠀⠀

$\sf : \implies\:{\bold{ Gain\% = \dfrac{3 }{5} \times 20}}$

⠀⠀⠀⠀

⠀⠀⠀⠀

$\sf : \implies\:{\bold{ Gain\% = \dfrac{5 }{1} \times 4 }}$

⠀⠀⠀⠀

⠀⠀⠀⠀

$\sf : \implies\:{\bold{ Gain \% = 5 \times 4 }}$

⠀⠀⠀⠀

⠀⠀⠀⠀

$\sf : \implies\:{\bold{ Gain\% = 12\% }}$
