If the numerator of a fraction T is tripled, and the denominator of a fraction is doubled, the resulting fraction will reflect an increase of what percent?
Choose the correct choice from the following answers:
A) 16 1⁄6%	B) 25%	C) 33 1⁄3%	D) 50%	E) 66 2⁄3%
This question can be dealt with conceptually or by TESTing VALUES.   We're told that the numerator of a fraction T is tripled and the denominator of that same fraction is doubled. We're asked for the resulting increase, in percentage terms, of that fraction.   Let's TEST 2/1   If we triple the numerator and double the denominator, we end up with....   (2x3)/(1x2) = 6/2=

3   Since we're increasing 2 to 3, we're increasing that fraction by (3-2)/2= 1/2 of itself = 50%   50%
