$\huge \underbrace \mathfrak \red{Explanation}$

$\tt Let\: the\: CP\: of\: one\: article \:be = 1 Rs$

$\tt Then \: the \: CP \: of \: 50 \: article =50 Rs$

$\tt Then \: the \: CP \: of \: 10 \: article =10 Rs$

$\tt \huge{\orange{A/q}}$

$Sp \:of\: 10\: article = CP\: of \:50\: article$

$Sp\: of\: 10 \:article = 50\: Rs$

$\green {Gain = SP - CP }$

$\red {Gain = 50 - 10 }$

$\purple {Gain = 40 }$

$\red {Gain\% = \large{\frac{40}{10}} ×100}$

$\red {Gain\% = 400\% \:\:}Ans$
