Answer 1

Answer:

Step-by-step explanation:since , pranita gets 40% in 1st subject

therefore,

      2x=40

=>x=20

now,

the mark she get in 2nd subject is---

   4x

=4*20 (putting the value of X)

=80

and in 3rd subject she gets

     3x

=3*20

=60

Answer 2

Answer:

let the ratio of subjects be x

1st subject=2x

2nd subject=3x

3rd subject=4x

Given,

Percent of 1st subject is 40%

so, 2x=40

x=40/2

=20

Percent of 2nd subject=3*value of x i.e, 20

=3*20=60

Percent of 3rd subject=4*value of x i.e, 20

=4*20=80

Therefore, she get 60% in 2nd subject and 80% in 3rd subject
