Answer 2

Answer:

The value of $(3a + 5b): (3a-b)$ is $7:1$.

Step-by-step explanation:

It is given that $a : b=2:3$

We need to find the value of $(3a + 5b):(3a-b)$.'

From $a : b=2:3$

$a/b=2/3$

$3a=2b$

Hence,

$(3a + 5b):(3a-b)=(2b + 5b):(2b-b)=7b:b$

$7b:b=7:1$

Hence, as per the given information, the ratio is $7:1$.

Option (ii) is correct.
