Question

If 24% students bought their lunch and 190 brought lunch from home how many students are there?

Answer 1

Answer:

250

Step-by-step explanation:

24% students bought their lunch

190 students brought lunch from home

Let us assume

X as the total number of students

Y as the number of students who bought their lunch

Then the total number of students which is x should be equal to number of students who bought their lunch which is y + number of students who brought their lunch which is 190

Given

(24/100)x=y--------------a

W.k.t

X=y+190

Y=x-190

Substitute this in eq a

(24/100)x=x-190

If u solve this u will get 250

X=250,that means total number of students
