Answer:

Answer => (C)20&30

Step-by-step explanation:

Ok so Her it is,

Let the ratios be 2x and 3x respectively,

so,

\frac{2x+5}{3x+5} = \frac{5}{7}

so,

7(2x+5) = 5(3x+5)

14x + 35 = 15x + 25

14x - 15x = 25 - 35

-x = -10

x = 10

then thde numbers are 20 & 30 respectively..

Answer is c) 20 and 30

2x +5/ 3x+5= 5/7

14x+35 = 15x +25
X = 10

2x = 2*10 = 20

3x = 3*10 = 30
