1. CSCA Math December 2025 Past Paper
   The point $(-1,3-\pi)$ lies in which quadrant?
   • A．Quadrant I
   • B．Quadrant II
   • C．Quadrant IV
   • D．Quadrant III
   Show answer & solution

   Answer: D

   Answer: D Since $3-\pi<0$, both coordinates are negative. The point is in Quadrant III. Choose D.

   Which point lies in the third quadrant?
   • A．$( 1 , - 2 )$
   • B．$( 1,2 )$
   • C．$( - 1 , - 2 )$
   • D．$( - 1,2 )$
   Show answer & solution

   Answer: C

   Third quadrant requires $x < 0$ and $y < 0$. Only $( - 1 , - 2 )$ satisfies this.

   If point $P(x, y)$ lies in the second quadrant, then point $Q(2x, 3y)$ lies in
   • A．the fourth quadrant
   • B．the third quadrant
   • C．the second quadrant
   • D．the first quadrant
   Show answer & solution

   Answer: C

   $P$ lies in the second quadrant $\Rightarrow x < 0$, $y > 0$, so $2x < 0$ and $3y > 0$. Hence $Q(2x, 3y)$ also lies in the second quadrant. Choose (C).
