Answer:

165:169

Step-by-step explanation:

Given:

a : b = 2 : 3 and b : c = 2 : 3

Formula Used:

If a : b = x : y and b : c = y : z

Then, a : b : c = x : y : z

Calculation:

a : b = 2 : 3 ---(1)

b : c = 2 : 3 ---(2)

⇒ a : b : c = 4 : 6 : 9

Now, (3a^2 + b^2 + c^2) : (a^2 + 2b^2 + c^2)

⇒ (3 × 4^2 + 6^2 + 9^2) : (4^2 + 2 × 6^2 + 9^2)

⇒ (3 × 16 + 36 + 81) : (16 + 2 × 36 + 81)

⇒ (48 + 36 + 81) : (16 + 72 + 81)

⇒ 165 : 169
