Answer 1

Answer:

total student = 420

number of boys = 280

Step-by-step explanation:

girls are 140

and it is given that girls constitute 1/3 rd part of total students

so lets say total students are x

given 1/3 x = 140

so x = 420

now number of boys = 420-140 = 280

Answer 2

Answer:

total number of students = 420

no. of boys = 280

Step-by-step explanation:

Given that

the no. of girls in a school = 140

and 1/3 part of students are girls

let the total no. of students= x

given 1/3x =140

so, x =140×3

×= 420

So, the total no. of students were = 420

also we have to find the no. of boys = the total no. of students— the total no of girls

=420—140

the total no. of boys in a school = 280
