• A. $50$
• B. $100$
• C. $150$
• D. $300$

Answer 1

The correct option is D $300$

	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 $=400$

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

$x+100=400$ $\Rightarrow x=300$

$\therefore$ Number of girls who like Mathematics $=300$
