Answer:

600

Step-by-step explanation:

Note: I have solved this question by 2 methods.

                                               

                         1st method      

                                           

                     

No. of boys = 0.8

Means no. of girls should be 0.2.

Given that,

0.2 girls = 150

Therefore,

0.1 = 150/2

0.1 = 75

                                                             

Now, We have to find no. of boys.

And we have 0.8

Therefore,

                               

=> 8*75

                 

=>  600

                                             

                    2nd method

                                   

Let the total no. of students be x

=> 150=8/10

=> 5X-750=4X

=> X = 750

=> 750-150

=> 600

                                                         

In this question, we have to just find no. of boys. Girls are given as 150 and they are 0.2.

And boys are 0.8. So, by taking help of 0.8, We can know no. of boys.
