Question # 8
The total number of students in a class being 200, the ratio of boys and girls is 3:2. If 20 more girls
and 10 more boys join the class, what would be the new ratio?​

Answer 1

Answer:

13 : 10

Step-by-step explanation:

because 3+2 = 5.

so 200/5 = 40.

x=40,

so (x) × 3: (x)×2.

then it is 120:80 .

if we add it is 120+10 : 80+20.

it's = 130 : 100.

it is equal to 13 : 10.
