Question:−

Find the C.P., when S.P. = ₹1575 and gain = 5%

\sf\Large{\underline{\underline{Answer:-}}}Answer:−

Given,

• C.P. = ?

• S.P. = ₹1575

• Gain = 5%

As we know,

\begin{gathered}\begin{gathered}\\\;\sf{:\rightarrow\;\;CP\;=\;\bf{\dfrac{SP \times 100}{(100 + gain\%)}\:}}\end{gathered}\end{gathered}:→CP=(100+gain%)SP×100

Now, Substitute the values

\begin{gathered}\begin{gathered}\\\;\sf{:\rightarrow\;\;C.P.\;=\;\bf{\dfrac{1575 \times 100}{(100 \; 5)}\:}}\end{gathered}\end{gathered}:→C.P.=(1005)1575×100

\begin{gathered}\begin{gathered}\\\;\sf{:\rightarrow\;\;C.P.\;=\;\bf{\dfrac{1575 \times 100}{(105)}\:}}\end{gathered}\end{gathered}:→C.P.=(105)1575×100

\begin{gathered}\begin{gathered}\\\;\sf{:\rightarrow\;\;C.P.\;=\;\bf{\dfrac{157500}{(105)}\:}}\end{gathered}\end{gathered}:→C.P.=(105)157500

\Longrightarrow⟹ \sf{\cancel\dfrac{157500}{105}}105157500 = ₹1500

∴ The C.P. = ₹1500
