Answer 1

Let the total of students(boys+girls) be 'x'
x*40/100=150
Therefore,
x=150*100/40
=375

Therefore,
No of boys=375-150
= 225

Answer 2

The number of boys in the school is 225

Step-by-step explanation:

Let the total number of students be x

We are given that 40% of students are girls

So, Number of girls = $40\%x=0.4x$

We are given that the number of girls is 150

So, 0.4x=150

$x=\frac{150}{0.4}$

x=375

So, Number of boys = Number of students - Number of girls

Number of boys = 375-150=225

Hence the number of boys in the school is 225
