Question

The ratio of students in three sections A, B and C of class VI is 2:3:4. The total number of
students in these three sections is 180. From section C, if 20 students are shifted to section A
and 10 to section B, then what is the new ratio of the students in the three sections of class VI?

Answer 1

Step-by-step explanation:

Let the number of students in the classes be 2x, 3x and 4x respectively;

Let the number of students in the classes be 2x, 3x and 4x respectively;Total students = 2x + 3x + 4x = 9x

Let the number of students in the classes be 2x, 3x and 4x respectively;Total students = 2x + 3x + 4x = 9xAccordingtothequestion,

Let the number of students in the classes be 2x, 3x and 4x respectively;Total students = 2x + 3x + 4x = 9xAccordingtothequestion,2x + 123x + 12 = 811or, 24x + 96 = 22x + 132or 2x = 132 - 96or, x = 362 = 18

Let the number of students in the classes be 2x, 3x and 4x respectively;Total students = 2x + 3x + 4x = 9xAccordingtothequestion,2x + 123x + 12 = 811or, 24x + 96 = 22x + 132or 2x = 132 - 96or, x = 362 = 18Hence, Originalnumberofstudents,
