Is it A? (70lbs)
7% --> 3% difference to 10%
17% --> 7% difference to 10%
so 7:3 is the required mixture (since we are closer to 7 than to 17), hence 70:30.
Cheers,
André

Solution by AndreG is correct IMO. I'd doubt that this is a 700 level question (seems to be a pretty straightforward mixture problem), rather a 600 level question (or even lower).
You can also solve this problem algebraically:
Variable we look for:
x = amount of sugar sold at 7% profit
Equation:
10%*100 lbs = x*7% + (100-x)*17%
Solving for x you get x = 70 lbs
