Question

If the product of abscissa of point $A$($25,-15$) and ordinate of point $B$($7,k)$ is $1225$. Then find the value of $k$.

• A. 49

Answer 1

The correct option is A 49
Given,
Abscissa of point $A$($25,-15)$ is $25$.
Ordinate of point $B$($7,k)$ is $k$.
ATQ,
Product of abscissa and ordinate = $1225$
$25\times k=1225$
$k=49$.
Therefore, value of $k$ is $49$.
