Answer 1

Answer:

1:3

Step-by-step explanation:

Answer 2

Step-by-step explanation:

girls and boys ratio = 4:6

which means => 4x + 6x = 100

10x = 100

x = 10

so , total no of girls in class = 4x = 40

total no of boys in class = 6x = 60

now it's also given that among girls the ratio of maths to physics is 3:1

which gives => 3x + x = 40

4x = 40

x = 10

so total girl students studying maths is 3x = 30

and total girl students studying physics is x = 10

Entire class maths to physics ratio is 3:2

so , percentage of the class comprise girls studying maths

=( 30/100 ) *100 %

= 30 %

so the answer is 30%
