  3. $150$
  4. $300$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
   Like Mathematics  Dislike Mathematics
 No. of Boys                 $50$                     $y$ 
 No. of Girls                  $x$                   $100$

Total number of students $= 500$

Number of boys $= 100$
Number of girls $= 400$

$50 + y = 100$               $\Rightarrow y= 50$
