findingmyself · Answer

Let the original value of each cake be X, We need to find (2X-Discounted Price of two cakes)/2X 
 Statement 1: Cake 1=X Cake 2= \frac{3X}{4} , Total price is  \frac{7X}{4}  
 % Saved= (2X- \frac{7X}{4}) /2X=12.5% 
  Sufficient

Statement 2: Doesn't talk about the scheme price or discount.  Insufficient

Dereno · Answer

Martin bought two one pound piece cake. Let the price be P.

Percent saved = ?

Statement 1:

Martin paid the regular price for the first piece and paid three-fourth of the regular price for the second piece.

Amount paid = P + (3/4)*P = (7/4)*P

If he had paid the regular price for two pieces = 2P

Amount saved = 2P - (7/4)*P

= P/4

(P/4) = x% of (2P)

x% = (1/8) = 12.5% . Hence,  Sufficient.

Statement 2:

The regular price of the cake Martin bought was $10 per one-pound piece.

This statement doesn’t give anything about the scheme price. Hence,  Insufficient .
