Answer 2

$\huge \mathfrak \red{ \underline{ \overline{answer}}}$

$\mathrm \orange{S.P \: of \: T.V = 3240}$

$\mathrm\orange{Trade \: gains = 8\%}$

$\mathrm \orange{C.P \: of \: T.V =? }$

$\mathrm \orange{C.P = \frac{100 }{100 + g\%} \times \: S.P }$

$\mathrm \orange{C. P = \frac{100 \times 3240}{108}}$

$\mathrm \orange{C. P = 3000}$

$\huge\mathbf \pink{C. P \: of \: tv = 3000}$
