Answer 1

Answer:

option b answer 18,27. this is answer for this question

Answer 2

Step-by-step explanation:

Initially:

a : b = 2 : 3, therefore b = 1.5a

After:

(a+9) : (b+9) = 3 : 4, therefore (b+9) = 4/3(a+9)

Sub in b = 1.5a to get 1.5a + 9 = 4/3a + 12

Rearrange to get 1/6a = 3

Therefore a = 18 so b must be 27

Check:

18:27 = 2:3

27:36 = 3:4
