Answer 2

Given:

• There are 40 students in a class
• 2/5 of the total number of students are gírls

To Find:

• The number of boys in the class

Solution:

Here, we have said that the total number of students in the class are 40 and 2/5 th part of the strength are of gírls So now let's find the strength of girls

${:\implies}\sf No. of. Girls = \dfrac{2}{5} \;of \; the \; total \; strength$

${:\implies}\sf No\;of \; girls = \dfrac{2}{5} \times 40$

${:\implies}\sf No \: of\: Girls = \dfrac{2}{1} \times 8$

${: \implies}\sf No \; of \; Girls = {\purple{\underline{\boxed{\pmb{\frak{16}}}}\bigstar}}$

— Hence, The total number of girls in the class are 16

Now,

Let's to find the total numbers of boys in the class and in order to do that let's subtract the number of gírls from the total strength in the class

${ : \implies} \sf Number \; of \; Boys = Total\; strength - Number \; of \; Girls$

${ : \implies} \sf Number \; of \; Boys = 40 - 16$

${ : \implies} \sf Number \; of \; Boys ={\purple{\underline{\boxed{\pmb{\frak{ 24}}}}\bigstar}}$

— Hence, The total number of boys are 24

Therefore:

• The strength of Boys in the classroom is 24
