Select the correct option:
(1) In a class there are 300 boys and 150 girls. How many students are
there in the class?
(a) 300 - 150
(b) 300 + 150
(c) 300 x 150
(d) 300 - 150​

Answer 1

Answer:

3/5of300=3×60=180 equal to nu. of girls

So,boys =total students - nu. of girls

=300–180 = 120

Alternative method ,

Let total students be 1

Nu. of girls =3/4(given)

So ,nu. of boys= 1(total students)–3/5(nu. of girls)=1–3/5=2/5

Then,nu.of boys=2/5 of total students

=2/5×300 = 120

Answer 2

Answer:

b). 300 + 150

Step-by-step explanation:

there are total girls = 150

total boys in class = 300

so,total student in class

total student =no. of girls + no.of boys

". ". = 300 + 150

". ". = 450.

so total student in class = 450
