$$\frac{(2a + 6a − 3b)}{(2a − b)} = \frac{2a}{(2a-b)} + 3$$

Statement 1

$$\frac{-2a}{(b-2a)} = \frac{-2a }{ -(2a-b)} = \frac{2a}{(2a-b)} = 8$$

The value of the expression will be 8 + 3 = 11

Sufficient

Statement 2

6a - 3b = 3

=> 2a - b = 1

1 equation 2 variables. Insufficient

Hence, OA should be A

The exact eqn requires a simple simplification that being

3+ 2a/2a-b

(1) $$\frac{−2a}{b − 2a}$$=8
This exactly provides us with the answer =11
Therefore Clearly sufficient

(2) $$6a – 3b = 3$$
This isn't sufficient as it doesn't help in the simplification
Clealry insufficient

Therefore IMO A

Simplify the expression:
2a/(2a-b) +3

1.
2a/(2a-b) = 8

11

Sufficient

2.

Not sufficient

A
