D. None of these

this is according to me

Answer 2

Answer:

answer is A ) 36

Step-by-step explanation:

B)RATIO OF GIRLS TO BOYS =3:4

TOTAL STUDENTS = 28

TOTAL PARTS OF RATIO IS 3+4 IS 7

GIRLS IS 3/7 × 28 IS 12

BOYS IS 4/7 × 28 IS 16

SO 28 IS CORRECT

C)IF TOTAL STUDENTS IS 49

TOTAL PARTS OF RATIO IS 7

GIRLS IS 3/7×49 IS 21

BOYS IS 4/7 ×49 IS 28

SO IT IS TRUE

A)BUT IF 36 IS TOTAL STUDENTS

TOTAL PARTS OF RATIO IS 7

GIRLS IS 3/7 × 36 IS 108/7

BOYS IS 4/7 ×36 IS 144/7

THOSE RESULTS ARE NOT NUMBERS SO

THE INCORRECT ANSWER IS A
