1) Joe's weight is 80% of Tom

2) Tom's weight is 125% of Joe's Weight

I have chosen D . Please explain me if I am wrong .

Thanks in advance for your response.

Statement 1: I'm assuming this is meant to read "Joe's weight is 80% of Tom's weight"
(otherwise we have a Sentence Correction issue in which we are incorrectly comparing Joe's weight to Tom).
If the question reads, "Joe's weight is 80% of Tom's weight," then we can say that Joe's weight = 0.8(Tom's weight)
From this, we can conclude that Tom is heavier than Joe. SUFFICIENT

Statement 2: Tom's weight is 125% of Joe's Weight
In other words Tom's weight = 1.25(Joe's weight)
From this, we can conclude that Tom is heavier than Joe. SUFFICIENT

Answer = D

Cheers,
Brent

Hmmm, I'm not sure how that's possible. I'd be interested to see the explanation for that.

Okay - thanks.
It's safe to say that the answer is, indeed, D.
