Find distance between point $Q(3,-7)$ and point $R(3,3)$
Solution: Suppose $Q\left(x_1, y_1\right)$ and point $R\left(x_2, y_2\right)$
$x_1=3, y_1=-7 \text { and } x_2=3, y_2=3$
Using distance formula,
$ d(Q, R)=\sqrt{\square}$
$\therefore d(Q, R)=\sqrt{\square-100}$
$\therefore d(Q, R)=\sqrt{\square}$
$\therefore d(Q, R)=\square $

Pushpmala has invested ₹ 24,000 and purchased share of FV ₹ 20 at a premium of ₹ 4. Complete the following activity to find the number of shares she purchased.
Activity :
FV = ₹ 20
Premium = ₹ 4
MV = FV + ⬜
= 20 + ⬜
= ₹ 24
$\text { Number of shares } = \frac{\text { Total investmen }}{ MV } $
$=\frac{24,000}{\square}$
= ⬜ shares.
