Correct Answer: $(\frac{18}{13},-\frac{12}{13})$

Solution : Given: The line $3x–2y=6$. -------------------------------(1)
Comparing this to $y=mx+c$, we have,
⇒ $2y=3x–6$
⇒ $y=\frac{3x–6}{2}$
⇒ $y=\frac{3x}{2}–3$
$m=\frac{3}{2}$ and $c=–3$
Since the lines are perpendicular to each other,
$m_1×m_2=–1$
⇒ $\frac{3}{2}×m_2=–1$
⇒ $m_2=\frac{–2}{3}$
The line is passing through the origin. So, $c=0$
⇒ $y=mx$
⇒

Correct Answer: $75$%

Solution : Total students appeared in 2008 = 50 + 70 + 60 + 60 = 240
Passed students in 2008 = 50 + 70 + 60 = 180

Correct Answer: 600

Solution : Here SP denotes the selling price, CP denotes the cost price, and MP denotes the marked price.
Let MP be Rs. 100.
Discount = 10% of MP = $\frac{10}{100}​ ​\times 100$ = Rs. 10
SP = MP − Discount = 100 − 10 = Rs.
