Question

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

Answer 1

Hint: Use Unitary method.

Using unitary method,
$400$ more shares can be purchased in RS. $=25,000$
$1$ share can be purchased in RS. $\begin{array}{c}={\displaystyle \frac{25,000}{400}}\\ ={\displaystyle \frac{25,000}{400}}\\ =62.5\end{array}$
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.
