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
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

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.
Option A
