Here's how I see it.

Statement 1 shows the ratio between each of the sides. AB:BC:AC is 6:4:3. We don't know the lengths, by using the ratio we can find the angles. I think the only way is by using trigonometry. Sufficient.

Statement 2, if it were = instead of >, would be a right triangle, meaning that no, one of the angles is not smaller than 90 degrees. But if the lengths of sides AB and AC increase, but BC (hypotenuse) does not, angle A will get smaller, making the answer yes. I had to draw a right triangle on paper to really see this. Insufficient.

Hi thanks for the reply.

I have one Q. Using ratio in the statement 1, how can we find the angles. Please explain?

I just plugged in 90 degrees for each angle to see if the ratios would ever make sense. Simplifying the equation you get the following ratios:

B:2C
3B:4A
2A:3C

Plug in 90 degrees for any of the three variables and you'll see such a triangle is not feasible.
