Answer 1

Answer:

156.25

Step-by-step explanation:

$\large {\color{red}{ \underline{ \color{yellow}{Question}}}}$

5. By selling a book for 150, a person gains 20%. At what price should he sell it so as to gain 25%?

$\large \color{red}{\underline{ \color{white}{Solution}}}$

$\large{ \diamond} \small{Let \: CP = x }\\ \large{ \diamond} \small{SP \: of \: 1 \: book = 150} \\ \large{ \diamond} \small{Gain = 20\% }\\\\ATQ \\\\\boldsymbol{ \rightarrow} x + \frac{20}{100} \times x = 150 \\ \boldsymbol{ \rightarrow} \frac{120x}{100} = 150 \\\boldsymbol{ \rightarrow} x = \frac{150 \times 100}{120} = 125 \\ \boldsymbol{ \rightarrow}cp ={ \underline{125}}$

$\large{ \diamond} \small{To \: make \: gain \: of \: 25\%} \\ on \: CP\\\\ \boldsymbol{ \rightarrow} 125 + \frac{25}{100} \times 125 \\ \boldsymbol{ \rightarrow} \frac{12500}{100} + \frac{3125}{100} = \frac{15625}{100} \\ \\ \boldsymbol{ \rightarrow} \underline{156.25}$
