Question

# If Rs.$25,000$ more invested, then $400$ more shares can be purchased. Find the market value of each share.

$400$ more shares can be purchased in RS. $= 25,000$
$1$ share can be purchased in RS. $\begin{gathered} = \dfrac{{25,000}}{{400}} \\ = \dfrac{{25,0{0}{0}}}{{4{0}{0}}} \\ = 62.5 \\ \end{gathered}$
Hence, market value for each share is Rs $62.5$.
Note: whenever we need to give some relative data. For example, in $x$ amount of something, we got $y$ amount of other things. Then we usually use a unitary method.
