Answer 2

Answer:

Total number of girls students are 800.

Step-by-step explanation:

As per the data given in the question,

Let the number of boys be $b=1200$

And number of girls be $g$

It is given that 50% of boys and 40% of girls have passed given that 46% of the total number of candidates were successful.

so, $0.5b+0.4g=0.46(b+g)$

putting the value of b

$600+0.4g=0.46(1200+g)\\600+0.4g=552+0.46g\\0.06g=48\\g=800$

So, total number of girls students are 800.
