(JEE MAIN-2025)
Solution
Equation of chord with given middle point
$T=S_1$
$\Rightarrow \frac{3 x}{25}+\frac{y}{16}-1=\frac{9}{25}+\frac{1}{16}-1$
$48 x+25 y=144+25$
$48 x+25 y=169 \text { Ans. }$
$T=S_1$
$\Rightarrow \frac{3 x}{25}+\frac{y}{16}-1=\frac{9}{25}+\frac{1}{16}-1$
$48 x+25 y=144+25$
$48 x+25 y=169 \text { Ans. }$
