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 270. 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

Answer:

2x+3x+4x=270

2x+3x+4x=2709x=270

2x+3x+4x=2709x=270x=30

2x+3x+4x=2709x=270x=30now according to ratio;

2x+3x+4x=2709x=270x=30now according to ratio;2x=60 ----section A

2x+3x+4x=2709x=270x=30now according to ratio;2x=60 ----section A3x= 90-----section B

2x+3x+4x=2709x=270x=30now according to ratio;2x=60 ----section A3x= 90-----section B4x= 120-----section C

2x+3x+4x=2709x=270x=30now according to ratio;2x=60 ----section A3x= 90-----section B4x= 120-----section Cnew data:

2x+3x+4x=2709x=270x=30now according to ratio;2x=60 ----section A3x= 90-----section B4x= 120-----section Cnew data:section A= 60+20=80

new ratio----> 8:10:9

Answer 2

Step-by-step explanation:

2x+3x+4x=270

x=270÷9

x=30

2x=2×30=60

3x=3×30=90

4x=4x30=120

120 ka 20,60 ma add ho ja aga

=60+20=80

new ratio=8:9:10 ans
