Answer:

I don't know this language and answer

Answer 2

Step-by-step explanation:

Let total number of students be x.

Number of girls =775

So, number of boys= x-775

Given, 4x/9 are boys.

That means, 4x/9=x-775

4x/9-x= -775

(4x-9x)/9= -775

-5x/9= -775

x= (-775×9)/-5

x=1395

So, total number of students are 1395.

Hence, number of boys = 4/9×1395= 620

Hope it helps.
